Moto sekai ichi'i no sub-chara ikusei nikki (former top 1's sub character)
This has a manga and has over 300+ chapters. It is a great manga with fighting, leveling, and overall chill. It has a good balance with the different team members a swell. Honestly it's a good wholesome chill manga and I totally enjoy reading it. I wish this was translated properly since a blog does it but has only translated 95 chapters. In almost 7-8 months they only translated 10 chapters
