Cultural Research Club kouhai. Shares a class with Shino and attends the same karate dojo as Yui. Has an aloof personality, but has mellowed out somewhat since joining the CRC.

They've already had their bodies swapped like musical chairs, had their ages changed at random and experienced their deepest desires taking control of them without warning, but if you thought Heartseed was finished with Taichi, Iori, Himeko, Yoshifumi and Yui, you've got another thing coming! Now there's a new affliction going around, and the name of this peculiar bug is emotion sickness. As in, suddenly your emotions jump out of your body and sick someone else! Needless to say, that's more than simply awkward if you've got a deep rooted phobia like a fear of men or repressed emotions that you've been trying to keep hidden, but in some situations it can literally be deadly! What is Heartseed up to this time, and why is he making our heroes involuntarily share their innermost dirty laundry?<br>
