Something fun about the Kubo's friends chapters, is that it remembers us, how sad Shiraishi life is without Kubo. Since he always has her,in the majority of the chapter, we almost get to forget, that since he's invincible, he's always alone and not only that, no one even remembers him, not even at home, only his brother seems to get contact with him. At the end of the day, Shiraishi never made sleepovers, got hugged by friends, talked about his grades or shared food. That are all things that he got to do when Kubo appeared in his life. When he said chapter ago, that he's not to her than a classmate, is because Shiraishi doesn't know what means to have friends or the be important to someone. Kubo's friends chapters, are always cute and fun, but they have this bittersweet felling, because it brings us to the fact, that being a "mob", is sadder than we can see
