It's confusing but also makes sense that they all ended up friends, because they're all misfits and have been bullied to varying degrees. Mimit is horribly shy and timid, and was bullied by other monsters. She gradually got better after Goblin/Wasabi befriended her. Aki is bullied because she's too kind and also her throwing up when revived. She's also/i] gotten better (and stronger) since Goblin was nice to her and eventually befriended her. Granite is bullied by her parents' maids, and disliked by most heroes and adventurers because she's kind of crap at fire magic and way too aggressive, getting herself and her party members killed. And Goblin is sorta bullied by heroes and adventurers who just want to kill her because she's a Goblin.
