Matsumoto Setsuna is the younger twin sister of Kentei Academy’s manga club president, Matsumoto Senri. Extremely similar in appearance, the two share what can be best described as a sportingly antagonistic sibling relationship, where Setsuna mockingly refers to her older brother as “onii-chama” while Senri has labeled his sister “Kimouto” (disgusting little sister). Originally attending a different school from her brother, at the start of high school she also begins to attend Kentei. She is able to deduce on her own the fact that gothic lolita fujoshi “Amane” is actually her brother’s male classmate, Miyano Amata.
Setsuna is friends with a fair number of fujoshi, such as Gen’ei Ryou (though primarily online and through mahjong), and the manga club’s Takaide. Unlike many of her peers, she enjoys but is not maniacal about Omakase Tentel, and is far more interested in titles such as Hameai and the genre of construction tool personification yaoi, for example Hammer on Nail action. She can often be seen giving a wry smile while saying, “Aha.”
Not above pairing her own brother with other people (though doing it partly because she knows it gets under his skin), Setsuna’s facial expressions belie the fact that the gears are constantly turning in her head to turn anything and everything into a BL situation. One example is when she becomes fixated on a pen and its cap, with the pen being the seme.
