Yachiru Kusajishi encounters an old friend named Masayoshi, who saved a girl named Mayu from a hollow. Masayoshi starts to tell the two about how a hollow killed his wife. Mayu, having had her parents killed by that same hollow, starts to feel a bit close to Masayoshi. Yachiru goes back home to Kenpachi, and she remembers that Masayoshi used to be close to her in the past. She goes to see Masayoshi and Mayu again the next day, and Masayoshi kills another hollow that only he could sense. Masayoshi plans to leave the following day, and Mayu asks if she could travel with him. However, Yachiru, before leaving again, privately warns Mayu not to get too close to Masayoshi. The following day, Masayoshi protects Mayu from a group of hollows, asking her to accompany him in his journey. Yachiru jumps between the two and reveals that Kenpachi told her how a hollow possessed Masayoshi, as proven when his love for sweets and the memory of his wife's name were now gone. Yachiru also says that Masayoshi had killed his wife accidentally and mistook himself for some other hollow. Masayoshi at first does not believe it, but Yachiru insists. He begins to transform into the hollow in his panicked state. Just then, a hollow shows up behind Mayu, and Masayoshi jumps in and kills it, fatally wounding himself in the process. Masayoshi dies happily in Mayu's arms after having some konpeitō from Yachiru, remarking how good it is.
