Yuki's sister Mika is married to the great producer Seguchi Touma, who used to play in the band Nittle Grasper, of which Shuichi is a fan. To succeed, Shuichi's band, Bad Luck, must obtain Touma's support. Yuki's sister proposes a deal to Shuichi - he will convince Yuki to recontact his family, and she will ensure her husband's support for Bad Luck. Shuichi refuses the deal, but decides to convince Yuki to see his family anyway. Yuki suspects his sister's involvement, which annoys him because he thinks Shuichi capitulated. His annoyance can be seen in the concert which becomes a total fiasco. Fortunately, Ryuichi Sakuma, the experienced singer of Nittle Grasper was in the audience, invited by Touma, and helps them. This greatly cheers Shuichi as he is singing with his idol.
