The Mascot of the Volleyball Boy Karasuno Family

I heard that there is Karasuno High School in Miyagi. Karasuno High School has a volleyball club. There is a little guy in the volleyball club who is even smaller than the little guy. The little man was very dissatisfied with others calling him "little man". It's a pity that he is a small man. So the little man got angry. The ball served is "Duang Duang". It looks very powerful. But everyone still regards him as a mascot. Motto: A small man can do great things
