Ixion Saga DT, Kono Subarashii Sekai ni Shukufuku wo! Recommendations
The Main characters from both anime are transported to a fantasy world. The World is like an RPG/MMO with guilds, classes, quests, and monsters. Both are NEETs who use their gaming/otaku knowledge to his advantage. They may seem weak but is actually very strong and reliable. Both Main characters are accompanied by others on his journey to get back to his own world. Both have comedy, action, and fanservice.
Both series involve a somewhat abnormal main character being dropped into a fantasy world. They make friends with a bunch of oddballs and go on a variety of comical adventures. Both main characters give a snarky running commentary on all the strange things happening around them, and tend to take a refreshingly pragmatic approach to getting things done.
Both are trapped in a fantasy world/video game rpg settings with a primary focus on parody, satire, and comedy in general. The main character of Ixion Saga accidentally falls on an antagonistic character when arriving in the fantasy world in episode 1 and inadvertently becomes feared as incredibly strong. He bands together with a party of misfit characters who all have irritating or endearing quirks that seem out of place for them. A strong muscly man who loves cute creatures, a transgender man-to-woman who somehow has massive boobs, etc. Also both series feature some wonderfully sloppy art and animation that really adds to the humor.
