I believe this is the 2nd manga series I have started reading about gender-bent characters apart from the first one with the "gender-bent co-workers."
The plot is relatively simple since we have two high school students who got whisked away in another world. Sure this sounds typical but one of the MCs was put in a female body, which by itself is unique. Luckily that isn't the only appeal, this series focuses on the two MCs navigating this fantasy world and overcoming things by facing it head-on.
There isn't anything special or talented about the MCs, they are practically borderline ordinary. The same could be said with this series, it's not mind-blowing or exceptional. It's just....the same usual stuff.
It is a good read though, nothing horrifying or sexual, really it stays in the middle and it works wonderfully.
