My Sister Is a Little Cute

P.S. (New work: The Delinquent Girl of Academy City. Please show it your support!) If Misaka Mikoto, ranked third among the seven Level 5 espers, has the straightforward personality of a boy, then her older sister, Misaka Kenkoto, who shares her surname, is a reserved girl.

Misaka Mikoto: I never thought I'd say this, but my big sister is actually kind of cute!

Kuroko: Protect the world's best sister-in-law!

(A wholesome story, no gimmicks.)
