Zastin is an absolute fkin troll, but his personality is kinda likeable. The multiple flash-forwards Rito had because of him were honestly kinda funny. The humour actually does land for the anime sometimes, and it's always nice to witness. The bond between Rito's sister and Lala is incredibly cute too. The animation for the perverted octopus and squid kinda threw me off, with the way it didn't match the rest of the animation.
