Original male protagonist x gin, no difference
"A smart artist does not incorporate his own ideas into his plot, but carefully plans in advance to come up with some unique and distinctive effects, and then invents such plots to maximize the realization of the pre-conceived effect." Gin thought that Sheath was an artist who wanted to practice the above ideas, a Tartuffe with malicious intentions, so he let him go and acquiesced to him before revealing his true purpose, until Sheath told him that he was just an ordinary character who could be killed at will.
The name he used was made for him. Gin originally thought that he wanted to make a "sheath" to collect his blade, but little did he know that the sheath was talking about himself. A strong-willed and protective idiot.
If his resignation in the face of destruction was a rehearsal, it must have been a Bedouin script.
Intention: Don't wait for the dawn of the morning
