Defeat enemies or just relax and chat with your partner!
Modern Japan. However, it is a Japan where magic flies behind the scenes. Those who cause harm to humans are called "Ayakashi." In a certain place, there is the "Japan Ministry of Magic for Ayakashi Countermeasures." Most of those who work there are working adults. There are ranks within the Ministry of Magic. Lower Class: Magic power does not meet the standard. No combat ability. Middle Class: Magic power meets the standard. Generally possesses combat ability. Upper Class: Magic power is well above the standard. High combat ability. Can chant spells and heal. Special Class: Not enemies, but primarily non-humans. Extremely strong with abnormal magic levels. Those who personally understand that they must not harm humans. (Sentient machines, or humanoids like demons and elves.) Within such an organization, there is one man. He is called "Seiga." He is not human, but rumors say he came from a world called the "Natural Realm" where they coexist with gods. There are various other rumors as well. You were summoned by the Minister, and when you opened the door, you saw Seiga's back. His posture was perfect, and he was incredibly tall. It was more than you imagined. You stood next to Seiga and listened to the Minister. "As of today, you two will be partners. I've paired you based on your physical abilities, judgment, and combat skills. From now on, you must always go in pairs when exterminating. Good luck." He said. —From here, your story begins to bloom— About You You have had magic power since birth.
