His path collides with the alluring demon princess Sophilia, but before she can explain how or why she's summoned him, they're threatened by a party of marauding heroes—and Echizen watches in horror as the "heroes" enact a genocidal massacre on Sophilia's demon friends.

With his life on the line, Echizen uses the world's magic to put his game developer skills to use in Sophilia's defense.

Abilities
As being Game Creator his knowledge very fit with his ability to conjure traps or " Magic Trap ", basically a practical form of tactics focused on nothing but victory, unsuited for one whose soul seeks out the truth of the true enemy. Yet that is why it is strong, and so brittle.

Sota is good tactician and cunning person able to tricked the enemy to able seize things in the broader perspective of him, such as diplomacy and logistics, in order to decide victory before the fighting even begun. His tactic's my used not for one-on-one combat situations, but for battles where many are mobilized. Stigma "It is when Sophie-sama, a member of the demon king's split her "Stigma" or "demonic core" with someone, and as a blessing, it manifest "any abilities that lay dormant in the person's nature". In the former world of Sato as much as i hate to say it, for who was even called the "God Trapper", we can even expect some superior abilities to appear. The Stigma is a carved seal that serves as proof of your contract with a Demon Ruler... That is, it would be a binding contract of master and servant and you cannot travel to another dimension with your master..
 * Being Contract as slave by Sophie, she can only boost Sota by giving her magic particle Crystal. Giving her it boosted 2x his ability Sota can performed it only one time used.
 * As called Magic trap, this ability able to create or form any kind of trap as the caster willed. As Sota's experience as Game Creator able to create any torture device or equipment, bigger or smaller.
 * The Magic Trap able to mark a region as his personal dominion by securing the surrounding as a booby trap.
 * The Ability itself never need certain places to active. It can generate or materialized any form of equipment. His eye's is usable as vision or surveillance to be able to perform any traps he can mark.

Sato's Magic is called "Magic Particles", But humans use some material called "Miasma" instead to make traps. And the amount of magical particles available depends on the environments. Being part of the Demon king's family, vast amount of magical particles accumulate within Sophie's body and by using the right-eye that Sato's received during contract that is, by using the "stigma" as a medium, you can harness them. The Strength of the connection of the "stigma" that harness her Magical Particles is relatives to your distance from her.
