@Khri_na He must go on a legendary quest to retrieve batteries for his Sexcalibur, so that he may embarrass both himself and everyone reading this manga further.
That or it has infinite charge because BS Isekai plot.
This is so bad that it circles back to being good and it KEEPS circling a full 360 degrees into bottom-of-the-barrel garbage. I'm amazed and not in a good way. It's not even that unique, Blade Dance has a similar premise but is way better in every aspect.
true. I have seen japanese novels in the isekai genre where the MC reincarnates as the spa, a vending machine, a sword, a backpack, the armor of a female hero, etc. ... so I guess this is pretty mild in that he ain't a vibrator.
