I think it would also mean something like Hajime's power over Hijiri is overpowering Hijiri's sense of self which is very interesting 😭😭 He'd 100% deny the offer earlier in the chapters if it was the usual Hijiri, but I think this is what Hajime exactly wants and what he means by his own title...
if it's just rinko that died but the other two are hospitalized (which, the story's language tells somehow) does that mean hajime only kills the women who tried to harm hijiri in some way but leaves the others alive...? idk but hajime gets VERY intense around people who could be a threat to...
