Arikura, Tomoko

有倉智子

Tomoko has been Nanako's best friend and support since childhood. However, Nanako's admission to the Sorority negatively affects their relationship and the trust Tomoko places in her.
Unlike in the manga, this rift in the anime—caused by lies told by Mariko—is resolved. Tomoko remains by Nanako's side, inciting and helping her as usual during moments of despair or difficulty.
Over time, Tomoko also befriends Mariko and defends her in front of others more than once.
Tomoko's presence in the anime provides a tone of "normality" and helps the viewer maintain contact with real life: while all the girls at Seiran base their lives on the Sorority's activities, treating them as a matter of life and death, Tomoko always shines in her simplicity, letting the viewer breathe in relief...
