Atsushi Nakajima vs. Nikolai Gogol

Atsushi Nakajima vs. Nikolai Gogol is a battle fought between Armed Detective Agency member Atsushi Nakajima and Decay_of_the Angel member Nikolai Gogol, who held government officials hostage during a secret meeting.

It happened at the onset of the Decay_of_the Angel' terrorism plot that framed the Agency in the midst of the murder society's killings involving four government officials within one week.

Prologue
Gogol poses a challenge to the Agency to save government officials he holds hostage in chainsaw seats within 30 minutes. Using his tiger speed, Atsushi makes his way to the location ahead of the others and is tasked to stop the timing device that will trigger the chainsaws on the hostages' seats. Deeming that a frontal assault may activate various traps in place, Atsushi opts to head underground in the emergency exit.

Battle
Along the way, Atsushi is held at gunpoint from behind by a floating hand, and he instantly evades its shot. Gogol surfaces and praises the rumored mantiger's abilities, afterwards introducing himself as Gogol. He quizzes Atsushi what he thinks his ability is, to which Atsushi correctly responds that it is a spatial-transfer ability.

Gogol expounds that he can link himself to any space removed by his cloak up to at least 30 meters away. Surmising that he cannot run or hide from Gogol's gunfire, Atsushi utilizes his speed and rushes at Gogol. The latter hurls his gun at Atsushi, who swiftly catches and breaks it with his tiger fangs.

As Atsushi approaches him, Gogol panically summons an electric pole from his cloak, propelling Atsushi away. Gogol warns him that he still has some more tricks up his sleeve, though he opts to pull out Atsushi's leg from his cloak to halt his movement. While Gogol tries to think of a "celebratory quiz" for him, Atsushi ponders on the clown's dangerous ability, more so in the hands of a terrorist.

Atsushi decides to stall for time and asks Gogol his reason behind their terrorism. Gogol cites two responses: first, he answers that he finds it fun and stabs Atsushi's severed leg from his cloak, and second, he answers that he merely wishes to gain freedom and therefore joined the Decay_of_the Angel to achieve such goal. Atsushi doubts his "real" reason for killing, so Gogol excitedly asks him which among what he said was a lie and advises him not to believe the words of a clown.

Aftermath
Gogol returns Atsushi his severed leg back from his cloak, though he is unable to take it from the floor. To attend to his guests, Gogol bids Atsushi farewell and teleports back to the mansion with his cloak, leaving Atsushi behind.
