Kotarou meets Kagari for the second time in the forest, and this time she makes contact with him by revealing her name. Kagari explains to Kotarou that only he can see her so he has to help her prevent Earth from falling into ruin, for this time there will be no re-evolution after destruction due to lack or resources. With a curt command to find fond memories of humankind that prevent conflict, Kagari sends him away. Pondering his chances, Kotarou decides that the main source of all these bad memories Kagari is accumulating up naturally for destruction come from the biggest conflict of all: Gaia and Guardian. Returning to Guardian, he reunites with Arata and Touka to glean special information, whereafter he journeys to Martel and joins Gaia as a summoner. Quickly, Kotarou excels at the art of monster-making and controlling and soon becomes an official member of Gaia, where he learns that Gaia is further divided into sub-groups belonging separately to Sakura and another man named Suzaki. Due to these divisions, Kotarou earns good contacts through Suzaki and returns to Kagari. However, she is very impatient and determined to raise her final judgement on Gaia and Guardian. In the end, Kotarou convinces her to trust him. Everything changes when he steps into Kotori's secret base and find Kotori, now three years older guarding Kagari as a Druid.
