Hola! Unfortunately, completely avoiding NTR is very difficult. Because it would require creating alternative scenes, otherwise part of the audience would be left without content and scenes.
Regarding Megumin, I think we shouldn’t fully stick to the original. After all, this is a parody, and new events and rules for the characters are introduced here.
Kazuma won’t be deprived of attention, and he’ll have his chance. This game is something between NTR and harem. Each character has their own story, with an incredible number of characters surrounding them.
Thank you for your opinion and advice!
