Buso Renkin Vol 8 (Manga)

Talk about being at the wrong place at the wrong time! High School student Kazuki Muto had no clue what he was in for when he rescued damsel in distress Tokiko from a monster known as a "homunculus." Disguised as humans - who actually eat humans - homunculi are malevolent creatures that affix themselves to people's brains, and once fully grown, the only thing that can annihilate them is a weapon called Buso Renkin!

Kazuki and Tokiko are on the run from the hunters of the Alchemist Warriors! Tokiko, now reduced to the size of a doll, fights alongside Kazuki and Gouta as they take on three of the hunters and Captain Bravo himself, whose past is finally revealed! As Kazuki and Captain Bravo's battle draws to a close, another Warrior Chief appears, as well as a man calling himself the Great Warrior Chief. What will it mean for Kazuki and his friends?
