In Illumica, an invasion of the enemy lands of Laft is being planned. As a sign of this, Kline goes into Laft undercover. Kline is an apprentice High Beast Knight (a Rivell), but he is definitely not at the top of the class. In Laft, Kline sets eyes on a shocking scene. Blood-soaked battles between enemy tribes, Darkness Energy widely misused, huge monsters called Vasists... And a young girl whose life is in danger in the midst of the fighting. As Kline is regretting his powerlessness, he hears a strange voice. 'Give me your life, and I will give you strength...' This is an epic story, where meetings and farewells, hopes and despair are all woven together. Justice Chronicles takes the authentic fantasy story and delivers it in a brand new style.

High Beasts, the fantastic weapons of which the Holy Messengers are so proud, and Guardian Beasts, ominous creatures which consume Darkness. In Justice Chronicles, two types of transcendental character, different but similar, lend their power in battles. During battles, they take damage in place of their partners. They use their limitless energy lavishly, and make use of powerful skills. If their anger explodes, the power released is beyond human knowledge! Don't miss the unknown battlefields the characters will visit together.
