Akiba Denki

Chapter one features Axl Low and Ky Kiske discussing the ethics of laws on a man that time travels. The second chapter has a long fight scene between Sol Badguy, Johnny, and some interesting tension between them. This was a doujinshi by one of the mangaka that worked on stories in several of the official Guilty Gear manga volumes, Akiba Denki (Zanzibar circle). Heliogenoms 4.0 is the 4th in a series of about 11 doujinshi, though the stories themselves aren't connected between volumes.
