That's the Japanese for the bubbles in question @RandomGuy2307 I think something better might be:
'Anyway, I'm going to kill an ordinary girl. If I kill her it'd be the first time I break my rule of not killing women' said aloud
'Well if it's the number I've raped it's uncountable' his inner thoughts
It was a one off bubble so it's not too important but 犯した is a word for rape.
@petra_lal I was talking about the inner thought bubble. The spoken (and relatively more important) one is very clear.
As you said, it is ultimately not important (I highly doubt we will see this character again), but since you asked for feedback, I felt it was worth mentioning. If no one has any complaints about what you did, it must have been a good job (at least, that's how it seems to me).
This MC kind of reminds me of Shera from “The Girl Who Ate a Death God”, but less violent and without the hunger.
He's thinking that normally he doesn't kill normal women, in this case referring to non-combatants.
The second part is him recognizing "Olivia" is the name of the woman who make him break that rule for the first time.
And yes 3rd part is that if it's rape he's done countless times...
The ねぇ here is informal ない, not the cutesy ねぇ~ someone might end their sentence in.
