Centuries ago, a mysterious energy called "Mana" revolutionized society, but it led humans to face an unprecedented crisis: the "Great Fall". After centuries of intensive use of mana, flora and fauna mutated, becoming more powerful and intelligent. Confronted with this threat, humanity takes refuge in the bastions, the 21 fortresses, to survive. Humans also begin to mutate, developing greater physical and intellectual abilities, as well as special powers called "systems" and "stigmata". However, a scientist warns of an even more devastating imminent threat: insects, organized and cruel, will mutate in turn. To counter this imminent threat, humans begin to study the beasts and learn to cultivate Mana like them. Mana exercises are created to accelerate this process and copy some of the characteristics, but changing exercises is difficult and risky. As the world struggles for survival, Rin, a semi-awakened with the power to perceive everything around him, finds himself at the heart of this turmoil, determined to find his place in a world in chaos and to protect those he loves from the surrounding dangers. ***************************************** Participate in WSA 2024
