Pseudo Mixed about it? If I were to choose, I'd say it's interesting to read, but it can VERY easily go down the "shitty" route. The name of the game is "keep your virginity or get shot and die" with the women trying their damn hardest to seduce the MCs "for the sake of the world" they say. Artist does a good job with the designs being ecchi and fappable, but if you're looking for that kinda shit, just go to a bloody hentai site. I'm honestly more wondering about what lead to this situation in the first place. If it turns into a crazy game of seduction, It's a solid nope for me. Kinda like what happened with Prison School. Really compelling and solid Ecchi art, but eventually just devolved to being full blown ecchi and lack of actual story...
Checked raws up to 25: Well. One chapter made the mystery compelling supporting the "To save the world" side. Buuuuuut the rest of it is seduction games...
