Canon
Hajime and Natsumi were classmates in the Reserve Course. When Natsumi first spoke to Hajime, she comments that he has no friends, and tells him she doesn't have any either. She says she's the sister of the Ultimate Yakuza, Fuyuhiko Kuzuryuu, and calls herself the "Ultimate Little Sister". Hajime points out that she doesn't have a talent, but Natsumi refuses to acknowledge that and says she'll do anything to get into the Main Course. Later, when Hajime meets her on the top of the Reserve Course Building, she tells him if she doesn't keep up with her brother, she'll get left behind. Hajime says he understands how it must feel lonely to get left behind. However, he also tells her there are other things just as important as talent, such as staying with her brother and making memories with him.
