On another manga site, "Heat" is listed as part of the "Rules / Hydra" series of Miyamoto Kano. This is actually written by Buronson. I think the scanners screwed up over there ! lol
This is an exceptionally realistic art where we can clearly distinguish racial diversity. It is my first time seeing in a manga characters who actually look like Asians instead of the typical westerners' looks. Of course westerners' looks, African or Asian or any other looks based on racial differences are all appreciated. Warning though there are nudity, explicit graphic content and violence involved.
