Kaida Haru (甲斐田晴) is a male Japanese Virtual YouTuber affiliated with NIJISANJI. He debuted as part of the 2020 unit "VΔLZ" alongside Genzuki Tojiro and Nagao Kei.

Profile
A prominent researcher from the Ouma Empire who studies "Evil/Demons". Since he is always immersed in his research within his residence, few people know what he really looks like.

Personality
Haru has a refreshingly boyish voice and loves to sing while playing the guitar. He's a self proclaimed introvert and an otaku, having been familiar with a wide range of old to new anime and manga. He will talk nonstop about an anime-related topic if its brought up and often makes references to them. He likes making puns and weird things like building toilets in Minecraft and occasionally songs with really odd chat suggested lyrics.

He has a playful and mischievous side that likes to play childish pranks but occasionally shows a motherly side especially to VΔLZ. He often gets affectionately teased by his seniors, though he himself has stated he wanted to be teased.
