Uta and Io enjoy their time in the Amusement Park they've finally got to visit together. They sit in the observation wheel and Io is seemingly happy! The best friends chit-chat about dates and, certainly, Sensei.
Right after they get down, Uta leaves for a minute to wash her hands, and Io reaches out for her phone. Suddenly, she is approached by two creepy and rude punks, who weren't hiding their malicious intent.
But this day, Io was lucky. Just as the situation got worse, Yuki appears from nowhere and beats them up with style. She explained to Io, that simply mentioning Yuki Yamaguchi's name shall be enough to defend herself next time. Io expressed her gratitude to Yuki, but noticed her unhealthy look and was worried. Just after this, Uta returned, and Io told her what happened.
