Oishi Masayoshi is performing the opening theme for the summer 2026 anime Hanaori-san wa Tensei shite mo Kenka ga Shitai and is also a featured performer at the Azur Lane 9th anniversary music festival in September 2026.
Oishi Masayoshi appears in two distinct projects for the summer of 2026. He is the opening theme artist for the television anime Hanaori-san wa Tensei shite mo Kenka ga Shitai, a romantic comedy that premieres July 11 on the ANiMAZiNG!!! block. The second promotional video for the series confirmed his role alongside the casting of Maaya Uchida, who voices a new character and performs the ending theme.
Separately, Oishi is one of the live performers at the Azur Lane 9th anniversary festival, branded as AZUR LANE MUSI9 FES. The event takes place September 5-6 at Shinjuku Sumitomo Building Triangle Square and Shinjuku Sumitomo Hall, with a focus on a live concert rather than a traditional exhibition. Other announced performers include May'n. The festival offers regular admission at 3,000 yen and premium access at 12,000 yen.
Both stories establish Oishi's active involvement in anime-related music and live events during the middle of 2026, with no further details about his broader career or upcoming releases beyond these two commitments.
