Inuyashiki, Volume 4

FRIEND OF AN ENEMYInuyashiki has put a stop to Samejima and his gang, but there are worse evils that he must face. Tokyo is still plagued by a string of cold-blooded murders that are being committed by Inuyashiki's cyborg counterpart, Shishigami, and Inuyashiki is the only one who can stop him. To prevent more senseless killings, Inuyashiki must learn how to master his newfound abilities, but he can't do it alone. Fortuantely, there's someone close to Shishigami who wants to stop his rampage just as badly, and his knowlege may be just what Inuyashiki needs to take down Shishigami.
