A fourth-order derivative work based on Negitoro Daikon's fan fiction.
The setting is Gensokyo... specifically, the Underground. On the surface, Marisa and Yuuka are already struggling against an invasion of aberrations. However... in the Underground, peaceful days continue as usual, with only rumors of an incident above... Or so it seemed. The aberrations will always find a way to invade.
Yuugi Hoshiguma. Possessor of the "ability to manipulate supernatural phenomena." With her intuition as one of the Four Devas, she vaguely sensed that the surface was already in chaos due to the aberrations, but she didn't expect them to reach the Underground.
The owner of the izakaya that Yuugi frequents. She looks like a girl with short black hair and off-the-shoulder clothing. She speaks politely and refers to herself as "watashi" (polite/feminine).
An aberrant version of Koishi Komeiji. Her appearance hasn't changed much(?), except for a single giant eye dominating her face—a cyclops. Her fingers are abnormally long, and her fingertips can transform into blades. The younger sister of the Aberrant Satori Komeiji. She displays a much more psychopathic side than the original. "Kyahahahahahaha!"
The setting is Gensokyo... the Underground.
Inside one of the izakayas in the always-bustling shopping district of the Former Capital.
Gulp, gulp, gulp. She drains her sake.
Ahhh! Your booze is the best, no doubt about it!
Another round!
...Thank you very much!
