(decided to make Arthur a Madoka-style magical boy XD
His witch, Viridios, is above
If you want another, just give me a character! I'll also make puella/puera magis for things other than Hetalia!)

Name: Arthur
Wish: Arthur is a lonely, bookish boy. He has no friends, and isn't noticed by anyone. No one knows his name, and even the teachers forget who is. Plus, as the middle child of six, his parents never paid any attention to him. All he really wants is for people to pay him attention, hopefully people who also like magic. So, when he sees a new magical creature who offers him a single wish to be a warrior, he takes it up instantly, knowing his wish exactly.

"I wish everyone would pay more attention to me!"

Theme: Magic
Weapon: Arming Sword

Costume details:
-green based
-intricate swirling designs
-long pirate style coat
-chain mail sleeves
-long boots

Descent into Despair:

The gift came, but it came in a corrupted way. People paid Arthur attention, but only to tease him. Only to mock him. In only a few weeks, it dawned to him that this was the answer to his wish.

"N-no! That isn't what I meant, you bastard!"

Runes: VIRIDIOS
Type: Lilypad Witch
Nature: Yearning
Description:

The Lilypad witch, with a Yearning nature. He is a starving witch, who doesn't want to be empty, but doesn't know how to fill the space, other than by eating all that comes into his barrier. Humans with vague ideas will wander aimlessly into his barrier, and Will never see him, leaving a perfect opportunity to eat. The only way to prevent him from snatching you before you can begin to fight is by looking him in the correct eye.

Runes: NYMPHADORA
Type: The Lilypad witch's minion
Duty: Entertainment
Description:

The Lilypad witch's minion, whose duty is to be entertaining. Several of them will run around, playing and writing stories to read aloud to the witch. She will always want to put on plays for the witch with the others of her kind, but can't find the witch. They can't fight, and are only there to entertain the witch.

Barrier: The Lilypad witch's layer is almost as straight forward as the magical boy who ended up creating it. As he transformed in his school, his barrier looks mostly like one, but overgrown with leaves and other vegetation. As you get deeper in, it becomes swampy, with thigh deep water below, and much more vegetation. At the centre of the barrier is a room made of crumbling walls. Inside, it is completely full of leaves and growth, making it almost impossible to find the witch.

I might do Alfred or Feliciano next, if you guys want more of this!
