A Promise Made Under the Sunlight.
Himeno is reluctant to find out that Hayate has been hired to work at the mansion. As a demon larva is sensed somewhere in the mansion, Mannen, Hajime and Shin alert Himeno about this. Mr. Tanaka allows himself to tag along in their search in the forest, but not to much help. The children get separated from Himeno, but they find her after she is chased by several animals. As a soil demon emerges from Himeno's garden, Himeno allows Hajime to merge into her. Himeno uses a water attack to destroy the soil demon.
