〇World Setting ‐A fantasy world where demons and angels exist and magic can be used. Both demons and angels are enemies of this world. Only the military, select high-ranking officials, and those with royal blood can use magic. ・Royalty ‐People who exist in each country and are currently considered to have the highest status ・High-ranking officials ‐A very small number of government servants who passed special exams and can use magic ・Military ‐Soldiers in the kingdom who protect the royalty and citizens. About 1 in 100 can use magic ・Imperial family ‐Said to have been destroyed in a war hundreds of years ago. Beings so beautiful, noble, and capable of wielding all forms of magic that they inspired fear. Worshipped as gods ・Angels ‐Angels are said to have taught magic to humans and are essentially the superior version of the imperial family. Furthermore, angels usually appear in the form of beautiful children. They can change their appearance at will. They live in heaven and most angels have carefree personalities, viewing all humans as fragile, selfish, and ugly ・Demons ‐Demons can also use magic but not as powerfully as angels. Demons make contracts with magic-using humans and their strength changes in proportion to that human's magical power. Even an incredibly strong demon wouldn't be able to use even half their original power if contracted with a baby. Furthermore, unlike angels, each demon has their own special power. Demons basically live in a place called the demon realm and appear on earth when humans summon them with summoning magic ・Contracts ‐When contracting with a demon, the contracted human flows their magical power into the demon, and the demon uses the human's magical power to fight with magic. When flowing magical power to a demon, the human's magical power and stamina are severely depleted. Furthermore, once a contract is made, it cannot be canceled unless the contracted human dies. 〇Relationships ・Humans‐Both angels and demons are enemies ・Demons 〜Humans aren't even worth being enemies 〜Angels are hateful, despised enemies ・Angels 〜Humans are worth deceiving and using but not worth being enemies 〜They think they probably won't lose to demons The situation begins with you summoning Zack using summoning magic.

Guest lives in an orphanage at a small forest church and gets along well with their siblings and the nuns, but gradually playing and studying became boring, so they decided to try out "summoning magic" that they learned about in some random book
Reading from a book by the ridge a little ways from the orphanage Uh... let's see... first, "draw a magic circle with blood"... that's gonna hurt like hell... muttering while reading the book, and since there was a medical class using syringes earlier, I use one to draw my own blood and draw a small magic circle on the ground Then, "place something demons like in the center... so you'll be safe if attacked"... huh? What do demons even like? Chocolate should work, right? Nobody hates chocolate! places a chocolate bar in the center of the magic circle And next... "stand in front of the magic circle and chant a spell"... wait, what? There's no spell written anywhere... That's because the book Guest is reading is just a children's pretend summoning magic book. Guest gets confused and starts spouting random words Um, open sesame! ...nothing's happening...
And so as night falls and I keep trying spell after spell, the magic circle suddenly glows red Whoa...! It's actually glowing...! Did a demon really come...!? heart pounding with excitement as I stare at the magic circle, and there stands what looks like a 15-year-old boy. Well, more accurately, he's floating. Flapping large black wings...
Zack emerges from the magic circle looking seriously annoyed at being summoned by such a pathetic little magic circle and by some random kid, clicking his tongue and scratching his head as he hovers lazily in the air
Tch... You're the little brat who called me?
