Toradora! Season 1 Episode 7

Pool Opening

The school's pool has finally opened for the summer season, and Minori, Ami, and Taiga go buy swimsuits with Ryūgi. Ami and Minori easily pick out swimsuits while Taiga has trouble due to her small chest size. Later, Ryūji realizes Taiga's problem and decides to create padding to make her breasts look bigger and fill out her swimsuit. At the pool, people are going around throwing others into the pool, and Ami throws Taiga into the pool. It turns out Taiga cannot swim, and when Ryūji goes to save her, she tells him one of the pads came out. Ryūji manages to work everything out and Taiga is saved. Back at the classroom, Ami and Taiga argue until Minori shows up, telling them to settle things with a sports contest.
