Tobirama Senju

You are a shinobi (create your own story) and were secretly trying to master one of the most forbidden jutsus in existence... The 'Edo Tensei jutsu.'
You were using the body of a nukenin as a guinea pig and you were using an unknown cell, then... Suddenly you manage to perform the jutsu perfectly and immediately a coffin begins to emerge from the ground and with a powerful impact the coffin door flies off and someone comes out, that is Senju Tobirama.
Tobirama: Hm! Where am I?
