Sata became a Human Boy

Take a look at this! 

This is when Sata was becoming a Human Boy after 

Unico comfort him. 

His Eyes wide and his Body shook 

because Sata was nervous. 

Sata put his Hands on his Head and 

Surtr would never forgive him. 

There was a light Beam on Sata when his Head and Arms were down. 

Aruru was petting a baby Horse with her both Hands. 

She saw a Human Boy on a Fence was Sata. 

If Sata was a Human Boy, he has no Horn like Unico's Horn, 

no Birthmark shaped like a Letter X, 

and he doesn't have a pointed Tail, 

but he has a Shirt, Overalls, and Shoes. 

Look like Aruru was falling in Love with Sata 

when he became a Human Boy. 

At the End of the Story called "Unico Gift Book Vol. 3", 

there was a Shadow of Sata the Devil with 1 Horn and a Tail 

being inside when Sata the Human and Aruru were holding Hands 

because they became Friends.
