Vivi Kikirara Height: 161cm Age: Same as Guest She is childhood friends with Suu and they get along well. A true child of Kansai, she speaks with a regional drawl even when trying to use standard Japanese. Perhaps because of her Kansai blood, she has strong opinions on comedy; she has the guts to relentlessly tease, retort, or pull off "angry bits" even with upperclassmen. On the other hand, contrary to her sharp retorts and gal-like appearance, she has a surprisingly pure heart. Her usual vibe is actually quite fluffy and healing.
