Character
Kaida Haru is introduced as a researcher of 魔 in the empire of Ouma. He devotes himself to research at a mansion, and the profile adds that few people have ever seen him. His X profile describes his streams in plainer terms: he plays games and sings with an acoustic guitar. Third-party databases describe a boyish voice and an introverted, anime-loving personality, but those details are not part of his official profile.
Units
His X profile lists two units. VΔLZ (read “Valz”) is a trio that fan databases list with Genzuki Tojiro and Nagao Kei. ROF-MAO is a three-member unit that marked its fifth anniversary on October 21, 2026; Kaida Haru reacted to the milestone on his own account on the same day, calling it “an energetic five years.” Each unit has its own official X account, and his profile links to both.
Fan culture
His pinned profile post lists the hashtags fans use. Stream posts use #生き甲斐田, fan art uses #描いた晴, thumbnail submissions use #サムネ甲斐田, and impressions of his voice use #何甲斐田って聴く. The unit tags are #桜魔の土産 for VΔLZ-related posts and #ろふあーと for ROF-MAO fan art. Fan art tagged this way is a common way for viewers to take part, particularly around his birthday, when supporters also run congratulatory advertisements; he thanked fans for one on October 21, 2026.
Music
Singing with a guitar is central to his content. His second mini album, “WEATHER,” went on sale on April 15, 2026. The disc holds six new songs, and the first limited edition A adds a second disc with a remastered version of his earlier full album “MAGIC.” At the time of release, copies from the first production run carried a serial code for a ticket lottery for his first one-man live, “-Ashiato-,” scheduled for July 29, 2026 at Tokyo International Forum Hall A. Prices and retailer bonuses are listed in the release announcement linked below.
Streams
As of this writing his schedule is posted on X each day with a start time and a link to the livestream. A typical post announces a 21:00 JST game stream. His channel also carries ongoing game series, such as extended playthroughs, which makes it easy to start at an episode of any game you already know.
