Sui Shijima, The Final Boss - S1.E24

After spending some time with him, Ohana invites Ko to come to the Bonbori Festival before leaving Tokyo again. As Ohana arrives back at the Kissuiso, they start getting a flood of reservations thanks to a positive review written by Satsuki. However, Sui insists that she intends to close the Kissuiso down after the Bonbori Festival. The next day, Sui takes Ohana with her to visit her husband's grave, where Sui suddenly collapses. Sui explains that she wanted to close Kissuiso down so the others could do what they want. Upon returning to the Kissuiso, the others are at odds against Sui, with only Ohana offering to help out with the Bonbori Festival preparations.
