Bonus Material

Thus Spoke the Kumokawa Sisters


In a limited release booklet from the GAMERS store accompanying the release of the novel, there is a short story about Kumokawa Seria and Kumokawa Maria, concurrent with the events of the novel. Maria visits Seria, worried for Tsuchimikado Maika who is moving away all of a sudden, a reference to the events of the previous novel.[2] Seria is dismissive with her concerns until it is shown that Maria only worried so much because this happened to her teacher Kihara Kagun as well. Maria says she has gotten over it, and hopes Maika doesn't carry a burden like her teacher did. She does wish however to have had a Christmas party doubling as a goodbye party for Maika.

Suddenly, Hamazura Shiage is jumping from building to building in the Processor Suit, passing by the Kumokawa sister's apartment, still trying to escape. Seeing his attire makes Maria think of her teacher.
