Toma is more important to the sister than the person she knows is using her to destroy parties with no purpose BUT she won't give them details about her for no reason (being her benefactor? Nope!)... Good writing heh!
The premise was good but the writing fell off quickily with the forced drama, not the worst to say but it was a good decision to make it short and sweet (imho ofc). Thanks for the work on the series and good luck to the author for the next work!
I thought the circle would have been crushed right from the start like in those "edgy" revenge isekai, it's cool to see the party pull through! (the circle crushed "boss" is in love with Toma ain't she? I mean that's one strong and weird obssession for him heh).
