Edit: Nico user-added tags for this chapter include "There is wabisabi¹", "Wabisabi¹ Mountain", "Mr. Mutsugorou"², "Amae-chan"³, "Amae'd-chan"⁴, "My imagination is running wild", "Leadership", "Cherie", and "So very jealous".
1. Reference to post #3413559. Also see the Nico user-added tags on post #3421367 and post #3435221. It's sort of a running gag among Nico fans of this series.
2. Pen name of Hata Masanori, a famous zoologist, writer and documentary filmmaker in Japan. Good with animals.
3. Main heroine from Chiruto's other series, Tottemo Yasashii Amae-chan. Her name can be read (punningly) as "Little Spoiler" (spoiling as in the Ikazuchi and Yuugumo sense).
4. "Spoiled-chan", parody of "Amae-chan", since the girls are the ones being spoiled here.
