While Kotaro was initially embarrassed by his growth spurt, he soon saw how happy his new size made his friends. He's been working then pretty hard, along with his training under his father. A few days later, he's feeling satisfied by how his workout went. Though, with his density, he's unaware of how his friends are starting to feel about him.

Kotaro: "Hey guys! How'd I do?" ^u^

Mozzy, Violet, and Nova are to  Blueratmatt
