I would argue this still requires the shota tag. All but one of the sex scenes in this release happens with the younger MC, in the prologue.
Also, most of the choices are either not translated, or are translated to the point that it's difficult to guess what you are actually deciding. Reading the dialogue that leads up to the choices is also of little help, as it suffers the same translation issue.
Renders and animation seem okay, but not understanding the story detracts from the impact of visuals.
Also, for those that pop in and cry about NTR, even without the damn tag being present, I don't see that happening here. MC is a stereotypical Chad/Dude-Bro/Power-fantasy, and the women are either one-night-stands or are also inexplicably powerful just like him.
All-in-all, there's a lot going on for a 0.1 release and more of a story being built that is trying to be more than just some guy in a school setting. A bit refreshing in some ways, while also frustrating with translation issues. There seems to be a lot of room for more story, though, as the main trio seem to have been doing other things before they made it to the "military".
