Takahashi Misaki Junjou Romantica Images

Misaki Takahashi (高橋 美咲 Takahashi Misaki?) (Uke of the Romantica couple) is the 18-year-old (19 in episode 8 of Junjo Romantica) little brother of Takahiro.
At the start of the series, Misaki is about to sit for his college entrance examinations. His dream is to go to Mitsuhashi University since that was the college his brother turned down so that he could begin taking care of Misaki after their parents died.
Although seemingly childish and brash, Misaki is later revealed to be a person who is simply adamant on insisting against doing anything that might be troublesome for anyone else. This is due to the fact that he still blames himself for his parents' death (believing that if he had not asked them to hurry home, they would not have sped in the rain and crashed). Misaki and Usami eventually begin a relationship together which puzzles Misaki, who is not outwardly confident about his feelings towards the older man because of his narrow view of a typical relationship. In the anime adaption, he is voiced by Takahiro Sakurai.
