A woman introduces her younger brother and tells the viewer to 'feel free to use him'.

The ad opens with a young woman in a volleyball uniform introducing a young boy named Sota, calling him her 'kid brother'. She then pats him on the head and tells the viewer to 'feel free to use him'. The scene shifts to a close-up of a woman with purple hair, who smiles and introduces herself to Sota. She mentions they met eight years ago at a tournament finals match. The scene then shows Sota looking surprised and blushing, and the woman with purple hair smiles and says she could never forget him because she had a crush on him. The ad ends with a quick shot of Sota looking flustered.
