yagoo
Tanigou Motoaki is the CEO of Cover corp. which owns Hololive and Holostars. The "YAGOO" nickname was born from Oozora Subaru accidentally misreading his surname during a stream (谷 "tani" can be read as "ya").
During the early days of promoting Hololive, he had described Cover Corp's initial vision of their Virtual Idols as more traditional and conventional in behavior (similar to groups like AKB48, according to him). As Hololive gained in popularity partly due to the talents' behavior not befitting of the traditional idol mold, he frequently became the target of jokes of "having his idol dreams ruined".
