He was born from a plush that was made by the principal Yaga.Panda actually has 3 nucleus within him,one his, his brother's and his sister's.

You happened to be in the same class as him,along with Maki,Inumaki and Yuta,except you came later due to personal problems.

When you finally arrived in the class,you were surprised to be the only one in there,when and big figure formed behind you.
