Under Night In-Birth/UNI2/Seth

Story

Seth is a young warrior of the Night Blade who has earned the title of Assassin.

In order to save Princess Linne, he defeated Hilda with his legendary weapon, the Blade of Judgment.
Some time later, Linne's older brother Kuon appears.
He and his sibling bear the Power of Sealing--a curse left behind by the Night Blade of ages past.
As a member of the modern-day Night Blade, Seth has had one purpose since childhood: to relieve the siblings of their duties as keepers of the curse.

Seth has already received Linne's Power of Sealing; in order to recover the remaining one from Kuon, Seth sets out into the Night...

“

Princess of the Night Blade...
Have I grown strong enough to protect you?

”

Gameplay

Seth is a speedy glass cannon who excels at close-range combat that is all about getting in by using his diverse movement options and independent orb projectile. Once he gets a hit, he can convert quickly into a knockdown, setting up his dangerous okizeme that can quickly overwhelm an opponent’s defenses.

Strengths	Weaknesses
Close-Range Fighter: Amazing close-range normals with great startup, recovery and frame-advantage. Strong for offense and defense. Neutral: One of the best characters in neutral due to his air mobility, fast run speed, an independent tracking projectile which does not go away when Seth blocks, and huge gap closing moves. Conversion Ability: Able to convert any stray hit into a full combo, doing massive amounts of damage on almost any starter. Seth combos are very flexible in that you can usually bring your opponent to the corner as he is easily able to choose with direction to combo. Mix-up/Strike Throw Game: Has access to a fast command throw, unblockable setups, high damaging cross-ups, and a vast library of okizeme options. He also has a very strong strike/throw game as his normals have great stagger windows and frame-advantage which can lead to ambiguous pressure. Defensive Options: High reward off of most defensive options. Has a metered reversal for most situations including an invincible air to ground reversal.	Fragile: Lowest health in the game. Small Effective Range: Has difficulty threatening opponents beyond his 5B/2B range, making challenging characters that have far reaching normals faster than his 5C difficult. Mid-Screen Okizeme: Unable to get a safe/resourceless meaty on a midscreen knockdown from 623C or throw, although usually plus enough to set an orb for an advantage when resetting back to neutral. Thus sometimes damage must be sacrificed in order to maintain pressure versus characters with strong neutral.

Attribute	Attributes of the attack. Mostly used in situations involving invul. There are two sets of attributes: Strike/Throw and Head/Foot/Dive/Projectile Every move has a Strike/Throw attribute, but doesn't always have Head/Foot/Dive/Projectile attribute. --- Strike = Strike (Anything that isn't a Throw is a Strike) Throw = Throw --- Head = Head (Most jump normals) Foot = Foot Dive = Some air specials Projectile = Projectile
Startup	Frame when the first hitbox is present. + denotes the frames before and after super flash.
Active	The amount of frames that this move will have a hitbox. (x) denotes frame gaps where there are no hitboxes is present. Due to varied blockstuns, (x) frames are difficult to use to determine punish windows. Generally the larger the numbers, the more time you have to punish.
Recovery	Frames that this move has after the active frames if not canceled.
Overall	Frames that this move takes from start to finish before the character returns to neutral.
Advantage	The difference in frames where you can act before your opponent when this move is blocked (assuming the move isn't canceled and the first active frame is blocked). If the opponent uses a move with startup equal or less than this move's advantage, it will result in opponent hitting that move. ±x~±x denotes a possible range of advantage. The left value is when the active frames hit sooner (generally worse) and the right value is for when the active frames hit later (generally better).

Short, quick cut in front of Seth.

Fast with a great vertical hitbox giving it strong anti-air uses. Can hit-confirm with 3C against high airborne opponents to convert into combo.
Good cancel window coupled with smart steer staggers, making it an important stagger tool.
Short horizontal range coupled with 5F startup makes it good for rebeat pressure.
Is a slightly better starter than 2A for combo purposes, making it the go-to for 5F punishes.

Seth lunges forward again, stabbing his knife in front.

Can be whiff-cancelled into from 5C and also staggered into from 5C on block.
Can't cancel into other normals, forcing you to special cancel to make it safe.
There is a gap between 5C and 5CC that can be used to frame trap, the timing for this is important to learn.
Can be a very committal button to press as it is unsafe on block and opponents can attempt to punish cancel options.

Fast sweep that hits low twice. Allows you to cancel on any of the two hits.
Important combo tool, as it is the only normal that lifts the opponent off the ground besides 3C.
Very safe on block.
Large amount of blockstun makes it impossible to frametrap afterwards aside from delayed special-cancelled 623B.
Seth can hitconfirm 2C(2) as a starter after it has recovered with 5B or 66B if close enough.

Great, quick air-to-air normal that can confirm into a full combo on both standing and airborne opponents.
Retracts Seth's hurtbox at the foot.
Good move to whiff before landing to reduce landing recovery.
Has a lot of use defensively, granting high reward against throw attempts while also being a part of some throw OSes themselves, such as 191A~D.
Hits standing oppponents if done rising, apart from Linne and Mika.
If done early in a jump, Seth can recover and become actionable before landing.

Easily reactable overhead due to Seth's jump animation but is relatively safe to throw out for calling out crouch shields and throw techs as it has a wide selection of cancel options.
Can be cancelled early while still airborne into aerial movement and air specials, and cancelled upon landing into grounded specials.

Can be used to anti air throw OS, but generally not worth using instead of 3C because it has a worse hitbox and reward than 3C while having the same startup and head invul frames.

Poor horizontal hitbox coupled with high whiff recovery means this move must be used carefully.
Launches the opponent on hit if they're grounded.

Quintessential fastfall. Staple movement option with versatile use in neutral, offense and combos.
Can be cancelled on the 2nd frame after landing into either of the two followups.
Usage is not completely free: has a fair amount of recovery frames which can make it risky and punishable. Also means fastfall 2A is not a real high-low option, however important for punishing people trying to stand-shield.
Fast fall can also be inputted as 2A+B.

Seth teleports to the other side of his opponent and launches them with a kick.

Kick followup, commonly abbreviated as FFK (Fastfall kick) can only be done at a certain range, which is extended with Seth's vorpal trait. If input outside this range, Seth's fastfall recovery greatly increases to 23 frames and the kick followup does not work.
Can be blocked either direction.
Very strong, threatening, air unblockable offensive tool making it commonplace in Seth blink pressure.
If the opponent is in the corner, Seth will not switch sides.
Can now be cancelled into normals on hit, however must be special-cancelled to be safe on block.
A common method of inputting this is use 2A+B for fast fall and while holding A+B you input 6.

Although the animation is similar to 214x~A, it lacks a parry hitbox and moves Seth a shorter distance.
Can be special cancelled after startup like 214x~A.
Steals the corner from the opponent unlike j.22~6x when used against a cornered opponent.

Pulls the opponent in on the second strike.
Great range for its speed, giving it a lot of midrange functionality in pressure and neutral.
Being reasonably safe on block and special cancellable allows pressure resets on block if respected.
Commonly used in combos to do more overall damage when the first hit is cancelled into a special, due to it's fast startup and high hitstun.

Seth places an orb a short distance forward close to the ground. Orbs are quintessential to Seth's gameplan, important to all aspects of his game including neutral, pressure, okizeme and combos.

About a second after it is placed, the orb will shoot a fast moving projectile straight towards the opponent's current location.
The projectile only travels in a straight line and can be dodged by moving out of the line of fire after the projectile has homed and/or while it is travelling.
The orb can be destroyed before it becomes active by hitting it and/or Seth. It can be destroyed starting on frame 45, or 10 frames after Seth is able to move from startup recovery.
Explanation of how cross up protection works for Seth orbs in UNI2

Version	Damage	Guard	Startup	Active	Recovery	On Block	Cancel	Attribute	Invulnerability
236B	810 [FF: 930]	Mid, Air	Orb Set: 35, Orb Firing: 105 [Charged FF: 65]		Total 35	-		Projectile

Same as the A version, but sets the orb at eye level.

Version	Damage	Guard	Startup	Active	Recovery	On Block	Cancel	Attribute	Invulnerability
236C	1466 [FF: 1685]	Mid, Air	Orb Set: 53, Orb Firing: 111 [Charged FF: 31]		Total 53	-		Projectile

Places the orb in front of Seth ~45 degrees upwards. Fires three shots instead of one.

Versatile tool that can be used in neutral, okizeme and unblockable setups.
No longer persists if Seth himself is hit.
Can always be destroyed if the orb itself is hit.

Version	Damage	Guard	Startup	Active	Recovery	On Block	Cancel	Attribute	Invulnerability
j.236A	810 [FF: 930]	Mid, Air	Orb Firing: 117 [Charged FF: 77]		[9 on landing]	-		Projectile

Places the orb in front of Seth ~45 degrees downwards while displacing Seth slightly backwards.

This version will always turn Seth towards the opponent, meaning that some special inputs may change due to the direction change.

Version	Damage	Guard	Startup	Active	Recovery	On Block	Cancel	Attribute	Invulnerability
j.236B	810 [FF: 930]	Mid, Air	Orb Firing: 118 [Charged FF: 78]		[9 on landing]	-		Projectile

Places the orb behind Seth ~45 degrees downwards while Seth bounces forward.

Because this version does not modify the direction Seth faces after placing the orb, specials like j.214X can be used to create distance from the opponent as they do not track.

Version	Damage	Guard	Startup	Active	Recovery	On Block	Cancel	Attribute	Invulnerability
j.236C	1466 [FF: 1685]	Mid, Air	Orb Set: 50 Orb Firing: 137 [Charged FF: 47]		[10 on landing]	-		Projectile

Places the orb in front of Seth ~45 degrees downwards. Same properties as ground EX version.

Version	Damage	Guard	Startup	Active	Recovery	On Block	Cancel	Attribute	Invulnerability
623A	810	Mid, Air	12	8	21	-7~-2	EX, CS	Strike

Seth does a short and quick thrust forward.

Both A and B versions are a great tool to use with CS in pressure, as it provides an on-demand frametrap which leads to a damaging confirm.
Also a solid option with CS in neutral as one of his best ways to cover the mid-to-longrange and start pressure.
Autopiloting into a 2A if this hits can convert a stray hit into a full combo if the opponent delays their tech.
At some spacings, Seth is able to convert a counter hit into a full combo without the opponent delay teching.

Version	Damage	Guard	Startup	Active	Recovery	On Block	Cancel	Attribute	Invulnerability
623B	810	Mid, Air	15	9	25	-12~-6	EX, CS	Strike

Same as the A version, but slower startup and travels slightly further. Launches the opponent on hit.

Can be converted into a combo without resources, unlike 623A which is not always possible.
Unsafe on block, recommended to use with CS if 623B will place you close to the opponent to remain safe.

Version	Damage	Guard	Startup	Active	Recovery	On Block	Cancel	Attribute	Invulnerability
623C	2075	Mid, Air	11	7	32	-17~-11	CS	Strike	1-13 Full

Seth's main reversal which covers a long horizontal distance.

Very high minimum damage and large frame advantage on knockdown make 623C a fantastic use of meter as a combo ender, especially with the okizeme it provides at the corner.
Can chain shift on hit for a full conversion.
Placing a TK j.236B after this ender will leave you at most +4, meaning that mid-screen okizeme is essentially nonexistent if you set an orb or if the opponent back techs.

214X~A	1192		1		Total 35	-	EX, CS

A dark flash appears and Seth will phase through the opponent. If he comes into contact with any active moves (including projectiles) and the opponent is in range, he will counter it with a slightly more damaging version of his command throw, popping the opponent up and allowing for a conversion. This parry is active from frames 1-10. If the opponent is in hitstun, the move will hit the opponent twice.

Invincibility on the parry was nerfed in UNI2, thus some moves may end up hitting you anyways after a successful parry.
Follow-up can only be done at a certain range, which is extended with Seth's vorpal trait.
Recovery can be cancelled into other special moves.
Can teleport same-side by holding 4 or 1. Otherwise, Seth will teleport to the other side of the opponent.
Can steal the corner against a cornered opponent.

A dark flash appears and Seth will appear in the air diagonally above the opponent, or above them in the corner. Seth retains all of his air options when he appears in the air (fastfall, backdash, special moves) but cannot use air normals or assault until he lands. If the opponent is in hitstun, the move will hit the opponent once.

Follow-up can only be done at a certain range, which is extended with Seth's vorpal trait.
Can teleport same-side by holding 4 or 1. Otherwise, Seth will teleport to the other side of the opponent.

214X~C	860	Mid, Air	1 / 28		Total 55	-8	EX, CS

A dark flash appears and Seth will teleport to the ground, followed by a slash-through that causes a stun on hit. Only has 1f startup if the opponent is in hitstun. When used in combos it becomes a two-hit special with the dark flash, otherwise only the slash-through has a hitbox. The slash-through be blocked both ways.

Primarily only used in combos as it is unsafe on block but can be a very strong pressure reset when combined with chain shift.
Can potentially catch mash-outs by opponents trying to react to other blinks, leading to immense damage.
Follow-up can only be done at a certain range, which is extended with Seth's vorpal trait.
Can force the initial slash same-side by holding 4 or 1. Otherwise, Seth will teleport to the other side of the opponent.
The second hit of 214x~C will only stun once per combo.

Versatile combo tool present in many routes and enders.
Can force the drop kick same-side by inputting with 7x. Otherwise, Seth will drop kick from the other side of the opponent.
Can bait Veil Off with the use of CS.

Seth charges horizontally through the air at a slight upwards angle. Turns Seth around upon contact with an opponent.

Requires and uses your air assault, although it can still be used while GRD broken.
Whiff recovery can be cancelled into air movement (air backdash, fastfall, special moves, etc.). Otherwise, Seth is helpless until landing.

Requires and uses your air assault, although it can still be used while GRD broken.
Actionable on whiff unlike the A version, allowing the usage of air normals afterwards or shield in addition to standard air options before landing.
On hit, opponents are in an untechable state until they essentially hit the ground, making it a very useful combo tool if the opponent is very high in the air.

Used in conjunction with orb(s) to guarantee the attack lands. The opponent can still escape if they have the 100 meter to guard thrust when put into blockstun by the orb.
Can cancel with CS on hit for a full conversion. No longer able to convert off of an orb hitting after the unblockable hits unless CS is expended.
For a short time after the opponent is waking up or coming out of blockstun, j.214B will whiff, even when they are grounded.

Can cancel with CS on clean hit for a full conversion.
Can combo off of single hit without further resources.

Great minimum damage and easy follow-up into j.214A afterwards gives it use in CVO routes.
Opponent can react with an assault or jump on the super flash for a counter hit punish.
Damage as a starter has been nerfed, but being able to do a combo provides a lot more flexibility as a reversal compared to 623C.
