Excel asks Mikami Hojo to form a commercial Contract to avenge Steiner. Keita goes on ahead with Kuro, who senses a Tera Guardian deep within the forest. Suddenly, Keita and Kuro are attacked by Kohaku and Tenma. Meanwhile, Nam heals Yakumo by altering his flow of Tera in exchange for food, in defiance of her observer status. Keita and Kuro manage to defeat the Mototsumitama with some help from PuniPuni, but are then trapped in a towering plant. Meanwhile, Excel and Mikami find Reishin, and they engage in battle against him, motivated by the deaths of their respective former Contractees, Steiner and Shingo. They seem to get the upper hand, however, as Mikami attempts to deliver the final blow, Reishin causes an explosion, leading to Mikami's defeat. Excel warns the others when they arrive that Reishin now has a Contractee. (Source: Wikipedia)
