Don-Chan (also known as the Dimensional Pied Piper) is the most powerful character in the Lapisverse, it's power exceeding that of Morgan Freeman's and Irregular. Known as the Dimensional Pied Piper for his ability to traverse the multiverse like butter and being able to summon characters from other universe to attack, Don-Chan seems completely unaware of his power.
He is a taiko drum with a white edge and four legs, a red face (which appears to be moly orange), and a light blue body. Don's dream is to share the beauty of Taiko with the world. He has a monstrous appetite and sometimes has expensive shopping at the Wada House which may take over for the worst. He usually ends his sentences with "Ta-don", meaning "Ba-dum" in Japanese.
In his home universe (The Taiko no Tatsujin Universe) he lives at the Wada House.
