Madoka

Madoka is the fifth Flame Dragon with the power to create barriers. The nature of Nadoka's flame is linear because to create a barrier he has to connect the fireballs, so four fireballs could produce a square barrier, three fireballs a triangular barrier, but two fireballs can't form a barrier because two points can't form a plane. By eliminating a fireball from the barrier the space of the barrier is reduced. He is a chubby ninja who speaks politely, but is rather sarcastic and vain. During his lifetime, his flame took the form of a tortoise.
