Review Detail of YAGOOEMON in Picking Up Beautiful Girls In The Post-Apocalyptic World!

I love the story until chapter 113 after MC become to so much heartless didn't give second chance to many Character, but the want that i can't not forgive is Ariel dead. she was have much story that can be explored in her background, and have good skill on Fire magic and Flight, at first i feel interested on her first appearance and have many hint that she will become hans allies or become his woman but... the author just kill the Character just like that i don't really mind if MC kill Veena (Underground boss) because she was evil but, not for this Ariel girl... she not evil like veena already lost my mood to continue this novel, even do if continue to reading i can't bear how many times he will killed many potential Harem?
