Tokorozawa Iku

She is one year younger and admires the protagonist as an older brother figure. Sacrificing her academic performance, she focused all her energy on physical activities and became a sports genius. She was strongly influenced by the popular manga "The Prince of Tennis" at the time and now receives enthusiastic cheers from girls as a prince-like character.

On the other hand, she approaches the protagonist like a friendly puppy and always stays by his side. She is good at reading the atmosphere and acts like a pure little sister.
