Takuma Momozuka & Agumon
A normal junior high-schooler, from a normal family.
One day, he and his friends joined a camping field trip.
But a mysterious force took him away, and threw him into another dimension
A reptile monster; that looks like a tiny dinosaur.
He first encountered Takuma in this bizarre dimension.
Going forward, the way Agumon Evolves will depend on Takuma.
