Takahi Ninomiya (二宮 タカヒ Ninomiya Takahi?) is a third-year student and one of Haruto Tokishima's senpai. She is in charge of the women's athletic department. She has a noble aura around and always acts as a high-class noblewoman at the academy.
Her relationship with Saki Rukino didn't go well, because Takahi saw Rukino as a former idol who does whatever she likes and neglecting her duties. When Rukino possessed Haruto's body, she made fun of Takahi, resulting in Takahi developing weird feelings toward Haruto. Takahi even dressed as a cheerleader to cheer Haruto in the fight (because of Rukino's prank) and acted nervous around him. Later on in episode 11, she became new JIOR's Minister of Foreign Affairs.
After Module 77 arrived safely at the Moon (neutral territory), she went to Earth alongside Haruto and several students.
At the end of episode 24, she is shown to have married Satomi Renbokoji (which now makes her Takahi Renbokoji).
Takahi's surname Ninomiya means "two" (二) (nino) and "temple, shrine, palace" (宮) (miya). Her married name Renbokoji means "communicating" (連) (ren), "priest's lodge" (坊) (bo), "small" (小) (ko) and "road" (路) (ji).
