After the escape of Accelerator and Index, Mike and his partner Dennis lead a squad of Hound Dog to eliminate Index and by proxy the patients of a certain hospital. Here, they disabled the security system of the hospital before rushing in and later discovers that the entire building has been evacuated due to a terrorist threat, indicating that someone has tipped the hospital off of their arrival.

Heaven Canceler laters calls Mike where he tells them to abandon Kihara Amata and never turn back, and warns them of Accelerator's brutality. Believing it to be a nonsense, Heaven Canceler tells Mike about the one who tipped them off. Immediately after a scream is heard from one of the squad's Hound Dogs, indicating that Accelerator is in the building. Heaven Canceler's last words to Mike is to not die as so he will help him as long as he is not dead.

The entire squad including Mike is later annihilated in 10 minutes by the arrival of the Accelerator.

Abilities
He is a normal human, though since he is a member of Hound Dog, he is capable of handling firearms.
