Shindou, Shuuichi

新堂愁一

Shuichi's initial ambition in the series is to follow in the footsteps of his idol, Ryuichi Sakuma, the lead singer of the band Nittle Grasper, by forming his own successful music group, Bad Luck.
At first, Eiri Yuki treats Shuichi coldly, but Shuichi persists through Yuki's chilly behavior, and eventually the two start a relationship after Shuichi helps Yuki deal with his tragic past and the events connected to Kitazawa Yuki. Shuichi's band also begins to gain fame, and a significant part of the series centers on his efforts to balance the demands of his career with his pursuit of Eiri's affections.
Shuichi possesses an innocent and energetic personality that reflects the uke stereotype. This trait is emphasized in the anime, where he frequently shifts into super deformed mode, which often undermines serious scenes. Despite this hyperactivity, he also displays determination and perseverance when he applies himself and focuses on his goals. This is clear in his drive to reach the top of the charts with Bad Luck and his aggressive pursuit of his love interest, Eiri Yuki.
