Ken Deshita and Log Horizon both have main characters who wake up in a different world and goes to adventure with a loli girl who looks up to them. Both have a laid-back tone with some cool MC moments with loli girl training to get better. Both anime share the same director and sound director as well.
If you're a fan of Log Horizon or RPG/game/fantasy world with adventurers, guilds, monsters, etc you'll like Ken Deshita.
