This fanfiction is more of a wish fulfillment. You don't need to expect it to be balanced in any way. If you proceed with reading it, you will see some broken skills, messed-up events, forced plot, and other absurdities. Tolerate them. This story was not meant to be good. It was meant to contain my fantasies and for me to have fun writing it.
The slice of life part intensifies chapter 24 onwards. If you felt like the earlier chapters are rushed, that is because they were. Read until chapter 24, where the story takes things slower.

Well, the R-18 tag there is not meant for sexual content, but for how there are mentions of brutal fighting. Targeting major blood vessels? Check. Bludgeoning? Check. Crushing and lots of gore and viscera everywhere? ... This one is more of a "Maybe check", but it makes an appearance in some chapters.
