Mint Aizawa (Sister)
Seiji Aizawa is one of the supporting characters in the anime series. He is Mint's older brother.
Seiji watched Mint's ballet recitals when he was younger. However, he was too busy attending his private school and getting involved in the corporate world to pay any attention to Mint.
Tokyo Mew MewEdit
In episode 9 of Tokyo Mew Mew, Ichigo made a plan to have Seiji attend one of Mint's ballet recitals. He didn't want to, but he did. Suddenly, a Chimera Anima, which was ballet-themed and made from a black swan, attacked him. He tried to protect Mint but got injured. Mint defeated the chimera anima in the end before her recital, and Seiji told her she was still important to him. He gave her some flowers and watched her ballet recital.
