Axel, the Hot-Tempered Half-Demon

Back when Princess Choco was trying to find ways to get Maeva out of the picture (or at least away from Wolf), she made a summoning ritual to invoke a powerful demon.

Because she was lacking some ingredients for the ritual, she only used half of the required items. This resulted in her summoning a Half-Demon called Axel. 

Bound by the spell of summoning, Axel has to follow the Princess everywhere. Short-tempered and grumpy in nature, the only thing keeping this half-demon obedient is Choco's magic word. Whenever she calls him ''Idiot'', he is instantly crushed to the ground by an invisible force.

When Choco joined Maeva's little party, Axel tagged along. He is slowly warming up to the group, especially to Yuka.
