Outbreak Company, Re:Zero kara Hajimeru Isekai Seikatsu Recommendations
In both, the male lead enters into a new world which involves with a different form of language, magic, maids and a harem. Also both the female leads are cute, pretty, and have the ability to use magic to defeat the enemies.
Both are set in fantasy type worlds where the main characters are basically otakus. Even though Outbreak Company is definitely more light hearted, I feel they share the same type of comedic approach. Also, cue cutesy maids. Did I mention they both have adorable maids?! Seriously, Myucel and Rem, just, just thank you.
