Majokko Shounen Magical Piece

When mysterious organisms called “Creatures” attacked the Earth, the government was powerless to resist their onslaught. As the world was gripped by fear, the development of “Magic” by reverse engineering the Creatures technology enabled the government to fight back.

Sakurai Hinata is your average high school student. Because of his aptitude for magic he is forced to transform into a beautiful girl and wield magic. A witch.

Together with four other boys with similar talents (except one who is forced to cross dress due to his low aptitude) they fight the increasingly powerful creatures.

At first, Hinata struggles but as time passes a feeling of camaraderie develops and maybe something far stronger than just camaraderie begins to take root between them.
