Rashōmon

Rashōmon (羅生門,) is the ability of Ryunosuke Akutagawa.

Description
Rashōmon is summoned from, but not limited to, Akutagawa's coat, and any other garments he wears. It transforms into an omnivorous, shadow-like black beast. Rashōmon has been shown to be completely adaptable and can switch between offense and defense to suit Akutagawa's needs.

It takes on a form of a shadow-like beast made up of what seems to be dark matter, drawn from inter-dimensional or other similar sources. It can consume anything, even space itself. Once space is split, guns or fire cannot hurt Akutagawa. However, its space rupturing capabilities needs time to activate, so taking advantage of this can give the enemy a window of opportunity to attack.It can be used for both offense and defense.

It is also capable of dugging and slicing the ground that can be used for stealth purposes and can serve as a foothold for attacks.

Despite it being a powerful ability, it can also be nullified by Dazai's No Longer Human.Moreover, it can also be easily overpowered by Fitzgerald's The Great Fitzgerald.

Types

 * Rashōmon: Agito (羅生門・顎,): Rashōmon is shaped into the form of a jaw to crush the target.
 * Rashōmon: Murakumo (羅生門・叢,): Rashōmon becomes a gigantic clawed appendage which extends from Akutagawa's arm. It can be used to carry out an attack.
 * Rashōmon: Higanzakura (羅生門・彼岸桜,): Rashōmon changes to a tendril-like form, wrapping around the target and lifting him up high in the air. Once at an appropriate height and distance, Rashōmon explodes into several finely-developed flower spikes.
 * Rashōmon: Sawarabi (羅生門・早蕨,): Several spikes spring up from the ground to thoroughly impale the target.
 * Rashōmon: Gokumon Agito (羅生門・獄門顎,): A variation of Rashōmon Jaws, considerably smaller in size.
 * Rashōmon: Renmon Agito (羅生門・連門顎,): Another variation of Rashōmon Jaws. Several Rashōmon Jaws are materialized by Akutagawa to deal with a devastating attack.
 * Rashōmon: Kurohatō (羅生門・黒波濤,): Rashōmon splits into several tendrils, possibly capable of striking down the opponent in numerous whip-like attacks.
 * Rashōmon: Tenma Tengai (羅生門・天魔纏鎧,): Akutagawa wraps himself with an exoskeleton-like armor using the black fabric.
 * Rashōmon: Tenma Agito (羅生門・天魔顎,): While Akutagawa is wrapped in his exoskeleton Rashōmon armor, he directs his power to his arms that take the form and force of Rashōmon: Jaws, used mainly for defense.
 * Beast Beneath the Moonlight–Rashōmon (月下獣羅生門,): While Atsushi activates Beast Beneath the Moonlight, he is wrapped by Rashōmon.
 * Beast Beneath the Moonlight–Rashōmon: Toramurakumo (月下獣羅生門・虎叢,): Atsushi's tiger claw is wrapped in Rashōmon and enhances its offensive power, enough to overwhelm a fully-powered Francis Scott Key Fitzgerald.
 * Beast Beneath the Moonlight–Rashōmon: Black Tiger's Supreme Claw (月下獣羅生門・黒虎絶爪,): Using the tiger's claws that can cut through abilities themselves and Rashōmon, Atsushi can stretch out that severed space and cut through physical armor and abilities. As it morphs into a divine blade, Akutagawa claims that no life form can possibly survive from this attack.

Moves

 * Spatial Distortion (空間 断絶,): Akutagawa can distort a space using Rashōmon.

Derivation
Rashōmon is based on the real-life Ryunosuke Akutagawa's Rashōmon, a short story based on tales from the Konjaku Monogatarishū. The story revolves around a destitute man, who ponders whether to resort to theft in order to survive or to starve to death.
