In one of the facilities, a terrible accident happened caused by a young girl named Reiha's summoning powers getting out of control. The girl was assumed to have died along with her family in the accident, but she survived, and was hidden with the Kascuza on the island of Jarazi, along with the result of the summoning, a young Summon Beast boy named Aldo. Seven years passed. Near their coming of age ceremony the spirits of nature suddenly began to go wild, and the two of them leave to discover the reason for the strange events, which is also an under kingdom.

In battle Reiha uses projectile attacks, and is able to cast sky/wind/earth/water/fire Spirit magic, curative magic, and buff/debuff magic. She has high magic power and SP but low attack and hit points. Aldo is the other main character in the game. He is a Summon Beast, brought into this world when Reiha lost control of her powers seven years ago. He loves Reiha's cooking, and listening to the wind. Aldo uses physical attacks in battle, as well as sword/axe/spear/fist skills, and buff magic. He has high attack power and hit points but is weak magically. He is a brave person and stands up for others in need. The game received "average" reviews according to the review aggregation website Metacritic.
