Thanks for the chapter!
There's a mistake on pg2. Sanja isn't a Mage but a Tamer. Other than taming a dragon as a Tamer I don't think she's used any magic of any type that a mage would use so far, especially considering the 'friends' she has.
Beelzebub is definitely falling for MC. Hopefully after this she learns some magic and raises her physical stats so can defend herself rather than relying solely on her Unique Skill Gross Eater in case it gets sealed again. MC is definitely overpowered as usually a dungeon's walls, ceiling and floor are extremely durable to point of taking a supreme effort to leave a scratch which auto-repairs so doesn't break from monsters rampaging or adventurers' upper tier spells and skills. I'm a little confused, was Yuuto really using an adult method to warm Beel up or was that her imagination combined with him holding her tightly? Michael is definitely a bigoted narcissist. Demon and human war was 500 years ago and condemning Beel to death and declaring her an enemy of humanity just because she's a demon is hubris and the same twisted logic Hitler had against Jews and non-whites. Frankly promoting genocide is a greater evil in my opinion. Granted Beel isn't a saint by any means but she only defended herself against humans who attacked her first and really likes human culture such as food and Japanese school uniforms.
