Sougo is one of the members of Idolish7 who excels in all aspects, both vocals and dancing. Many fans love his close relationship with Tamaki, which ultimately led to the agency debuting them both as MEZZO. He is the son of the famous CEO of the Ousaka conglomerate family and he was predicted to be the successor to the family business. However, his uncle's love for music was passed down to him, which made Sougo dream of becoming a musician and idol. Because of this, after his uncle passed away, his relationship with his family became increasingly strained until he finally decided to leave home and join Takanashi Agency as part of Idolish7.
