Gashu starts harrassing Rakesh Kumar Orton for being a "Non-Detective", stopping him from reaching his match and forcing him to fight. Kaidou interjects in for preying on the weak and challenges Gashu, which allows Rakesh to flee to his match.

Kaidou manages to defeat Gashu and prove his worth as non-detective, but has to unseal his deadly secret technique in the process.

When he hears the news that his friend Rakesh has gone missing announced by the Sonozaki, and everyone's apparent uninterest, Kaidou swears he will find Kaidou, no matter if he has to take on the entire Dark Reunion organization by himself, for the sake of his friend.

Kaidou, figuring that the Sonozaki are behind these freak accidents and disappearances, goes to face them directly.

He can barely manage to keep up with the both of them by himself, and when they see an opening, Shion uses her bracer knuckles stun gun.

When he is down in the floor, Rakesh appears seemingly as if to save him, but instead, lifting up a chair, Rakesh brutally hits and hits and hits and hits and hits him, and finally closes the steel chair on his neck, breaking his windpipe and sending him to the hospital. All for the sin of daring to see him as weak and trying to help him, he was punished.

BCW.pngde 8
Rakesh challenges Kaidou to a match to end him for good, but Kaidou willingly shows up to try and free Rakesh from himself or whatever influence has changed him from his way.

With his throat damaged still, Kaidou manages to defeat Rakesh back for what he did.

BCW.pngde 9
Kaidou gets ready to defend BCW with all his might, to put such a performance no wrestler will dare to go against BCW ever again. Rakesh walks in before Kaidou can leave and apologizes and leaves.

After his champion match is stolen by an atom, his match is against a man with a not-so-good track record, but apparently worthy enough to be the company's #2 draft pick, someone in which Kaidou senses both good and evil within... Ushiromiya Battler. However, despite all his training and his power, Battler is just relentless in this finale tournament and doesn't allow Kaidou to score even a single point.
