Gleipnir Vol. 6

Shuichi Kagaya is an ordinary high school student living in a boring little town, that is until he discovers one day that he can transform into a strange mascot-like dog creature with a cartoonish smile equipped with a big revolver and a large zipper down his back. After saving his beautiful and conflicted classmate Claire Aoki from a warehouse fire, he learns that there are others like him when Claire confides in him that her older sister Elena transformed into a monster before murdering her parents and that she is determined to track her down at any cost. Shuichi decides to join forces with her to help her complete her mission, but will her bloodlust and uncaring demeanor prove too much for him, or will he see things through to the end? Find out in this dark supernatural action series by Sun Takeda.
In Vol. 6, the duo investigate a crashed alien ship in the mountains in search of coins and end up making some new allies. With all the Gatherers that are after them, they can use any help they can get!
