Nico Sawamura's Links
Nico sees Shu as his little brother in some ways, always keeping by his side, letting him hide behind him whenever he was scared or frightened. After his confidence boost, Nico found himself feeling a bit proud and relieved, as now Shu won't have to constantly rely on him. After being defeated by Shu in the one-on-one battle during the Sports Festival, while he was proud for him, he did feel that his skills were lacking, and thus trained harder than ever.
Shu admires Nico for his skills, his quirk and his kindness, going out of his way to make sure Shu was alright and comfortable. For a while, Shu felt, like he wasn't deserving to be his friend, but he realized that the other needed him just as he needed Nico. After his confidence boost, the two still talk and interact, but not as much, simply because Shu is now able to talk comfortably with others. After defeating Nico in the one-on-one battle during the Sports Festival, Shu felt guilty, but at the same time ,elated he managed to defeat someone far stronger than he.
