Wataru Matoba
About
In stark contrast to the hot-blooded, idealistic, and optimistic Yuto, he is more cautious, realistic and pessimistic, often finding the negatives to Yuto's attempts to be positive. And yet, it's because he wants the band to be a success. He has an inferiority complex toward his older brother Kenta and wants to surpass him.
