He is part Seraph too though, so only time will tell.

Saegusa, student council president in Irregular at Magic High School. Tatsuyas world, from their first mission. She was dating Yuuji and was told about the chat group.

Poor Mayumi got forgotten.

A cliche multiversal system would be another. Never finished but it does have about 450 chapters. Saw you were reading the sequel to EPIC so I didn't recommend it. Difficult to find stories people started and actually finished that are good. At least for specific genre and when put on the spot. Glad to know we have similar tastes though given so many recommendations you are reading or have already finished.

I would suggest 'In HOTD with the Satou system' for a satisfying read that is complete and a decent length. Some in my list were never finished, so I can't really speak on those. Another good choice is something like In HP as a high human(HP x DxD crossover). I feel like the author continued past the best part to end that specific story though, so it is left unfinished.

Any specific themes you like? Or certain universes?

Not that I can recall. I would suggest Multiverse Gacha as something somewhat similar that does have lemons.
