Holy shit those chapters.
The author gives no shit about introducing characters, building tension, or even giving any decent screen time, and just skip through everything. Like, the whole prologue shtick of MC isekai'd and then getting used to world just takes a single page.
The only time it slows down is when it gets to the ecchi part, even then it still feels that it goes by so fast.
It's like they just condensed 2-3 volume of novel in these 5 chapter.
Why though? Isn't actually catching up to the original a nightmare for adaptation?
