I actually like this manga, despite being a female reader. It has all the tags & content I love especially Sci Fi & Isekai, albeit it is a shonen-ish otome kinda manga. The Ecchi part I didn't particularly mind, as the MC isn't a boob & skirt chaser although he has so many opportunities to do so - that's because he was a fully-fledged adult with life & game experience prior to being reincarnated, as well as he had faced a terrible girl before facing so many more terrible girls in the next life so he knew how to handle himself & knew what to do.
I recommend people that hates Ecchi, Harem or whatever you dislike to skip this manga, if not for the plot & such.
LOOK AT THE TAGS FIRST BEFORE READING & THEN COMPLAINING & GIVING BAD & STUPID REVIEW LIKE THE PREVIOUS/BELOW COMMENT (BEFORE MINE). There's one thing for being logical or morally correct, & there's another for being at the wrong place only to critise for the obvious reasons you shouldn't be in the first place. @bobberino7 take that. You shouldn't be here complaining like a Karen if you've read the tags thoroughly first. Ecchi mangas are made to be Ecchi for reasons young inexperienced girls simply won't understand.
See a yellow Ecchi tag, avoid it! Also, the MC was REBORN, THUS HE IS YOUNGER NOW IN HIS SECOND LIFE, THAN WHEN HE DIED PREVIOUSLY. READ CAREFULLY, OR AVOID TAGGED ECCHI MANGAS NEXT TIME, KIDDO. BYE BYE. Aunty's rant over!
