Well, that's an interesting solution to getting rid of bullies. Try and show your qualities so that they can't make fun of you.
But Azuma is lucky those kids were just teasing her, and not being big bullies. Because now she has friends, and her mom knows not to protect her too much. She's cute too, so I'm sure the boys won't mind having her around often.
Also, Yamamoto's story from the past might not be completely accurate. He did seem them from afar, after all. But whatever the case is, his advice worked this time. He's always willing to help, even if he does it in a very awkward way. No wonder Hattori really likes him!
Sakurama was pretty funny this chapter. She started the inception of the whole plan with how easily she shot down those targets. The shopkeeper was so glad he didn't need to close up shop early when she returned everything. He even let them lead the stall a while!
