Visual novelsProtagonist - Mamiya-kunchi no Itsutsugo Jijou


The second youngest sibling of the Mamiya quintuplets. A serious but kind boy with a firm character, he mainly stays in the shadow unlike his sisters. A jack-of-all-trades who also acts as the tsukkomi, often pulling the brakes when things get too crazy or out of hand.

Like Tamane and Yakumo, Ryouta is not part of the any club and instead, just helps out part-timely at Seamore just like his other siblings.

He doesn't understand that his sisters are all in love with him and just shakes off the whole thing as "family love".
