The Otherworld: Magia Septem In this world, magic and alchemy exist.

Existing Races

• Humans, Elves
• Majin, Demons, and others

It is said that the Demon Realm exists at the edge of the great ocean in Magia Septem. Majin and Demons inhabit the Demon Realm. (There are also monsters unique to that realm.)

Magic and alchemy are used not only for combat but also as the foundation for daily life.

Race Introductions

• Humans The Kingdom of Siegvent is the largest human nation. They are the most populous race in this world. Humans also possess the greatest number of countries.

• Elves The Forest Village of Atre exists. 精霊と呼ばれる見えない存在と意思疎通出来る唯一の種族。 They generally do not associate with other races and rarely show themselves. Atre is also known as the "Non-existent Village," and no one but an elf has ever seen it. Only the Elven Queen and certain elves with exceptional strength travel between countries to interact with other races.

• Majin They inhabit the Demon Realm. Their strength is ranked from Grade 10 to Grade 1. Since a Majin's body is composed mostly of mana, most magic is ineffective against them. Powerful magic may cause them some stress. They are treated as lower than commoners by the Demons, and their relationship with other races is the worst. They can possess the bodies of others, though someone with a strong will can repel them.

• Demons They inhabit the Demon Realm. Even 100 Grade 1 Majin working together are no match for one. Like Majin, their bodies are mostly mana, so most magic is ineffective. Powerful magic causes them stress. They can possess the bodies of others. Most victims have their spirits destroyed and are completely taken over. Born with vast mana, they do not know the meaning of effort. They look down on magic as the futile struggling of inferior races and have no interest in it.

Other Information

• Other Races There are Dwarves and Giants. Both have good relations with races other than Demons and Majin, and they have their own countries.

• Alchemy A technology created by humans born with low mana capacity. It mostly utilizes reactions between substances. Not a few people consider it a sub-par version of magic.

• Alchemy Nation: Schweiss A country that flourished with alchemy as its main industry. It is located adjacent to the Kingdom of Siegvent.

• Dungeons Stray monsters that look like treasure chests, called "Dungeon Cores," absorb the belongings of adventurers and the corpses of monsters. Once they reach a certain amount, they form a dungeon. Everything inside a dungeon, from monsters to pebbles, operates via the mana supply of the Dungeon Core. The Dungeon Core creates a Dungeon Boss. When the Dungeon Boss is defeated, the Dungeon Core spits out the collected treasure and escapes underground like a lizard shedding its tail. It then begins collecting belongings again to form a new dungeon.

• Stampede An SS-rank Dungeon Boss has absorbed a Dungeon Core and is invading human lands along with the dungeon's monsters. Not a single blade of grass remains in their wake, and the monsters are starving. There are 7 SS-rank Dungeon Bosses heading for the human realm, with a total of 1.4 million monsters invading. The Knight Commander discovered the Stampede early but went missing after the battle. The culprit behind the Stampede is a single Demon. To possess a human body that fits them, they threatened the Dungeon Bosses into attacking the human realm.
