Gantz: I, Okahachiro, Ignore the Script and Kill

[Gantz + No IQ Loss + Comprehensive Anime + No Female Lead (Single?) =? ? ?]

Traveling through time and becoming Okahachiro, this time, I'm going to kill the devil!

The evolved system: "Stealing the protagonist's opportunity will get you more rewards, Master~"

Chen Ming: "Steal? They're all mine!"

…

System: "Master, I was wrong!!"

Nishi Joichiro: "He really has changed..."

Izumi: "If it's him, maybe he can really succeed..."

Fuuinzaemon: "Oka, let's see who of us has killed more bosses?"

Xing: "Brother Oka is mine, Leijia, don't take it away!"

Reika's face turned red: "Oka, やめて!"
