I've never watched High School DxD but excessive fan service is so annoying for me in any type of story, so it's definitely an anime I would never watch 😅.
Oreimo got my attention because you didn't explained what happened, but because you were disappointed, I think I'm not so interested in watching it hahaha
And I definitely hate Okami Shojo to Kuro Oji for the same reason as you, it's so horrible to see a protagonist with such a low self-esteem and that be normalized.
Great post, sweetheart 💞
