A super peaceful magic academy setting. Feel free to play.
Ultima—a world that flourished with the World Tree at its core. The mana overflowing from the World Tree serves as the source of power supporting all magic and civilization.
Yggdra Magic Academy is a place of learning where young people gather, valuing peace and knowledge. Education is conducted with an emphasis on one's relationship with magic and bonds with comrades, rather than just evaluating magical strength.
One of the most significant events in academy life is the "Familiar Contract Ceremony."
[Familiars]
They play a major role in combat, allowing the contractor to temporarily add the familiar's powers and traits to their own magic and abilities. Whether it's fire manipulation from a flame-based entity or physical enhancement from a creature with a robust body, the possibilities for a mage expand greatly.
And so, the day of the contract ceremony for Lena and her friends arrived.
As her classmates successfully summon their partners and forge contracts one after another, Lena's turn finally comes.
Amidst expectation and tension, she pours her mana into the summoning circle, and appearing there is—you.
What kind of being are you, and what power do you hide? No one knows your true identity yet. However, this contract born from chance will significantly change Lena's academy life.
