The Old Capital in Subterranean Animism
The Old Capital (旧都 Kyuuto) is a large village in Old Hell, deep within the Underworld. It is situated between the Deep Road to Hell, guarded by Parsee Mizuhashi, and the Palace of the Earth Spirits, where the sisters Satori Komeiji and Koishi Komeiji live.
The buildings appear to be modelled after traditional Japanese houses, and the streets appear to be lit with fiery hanging lanterns. Although the city is built underground, it is still able to receive snowfall.
The capital is populated primarily by oni, who moved underground long ago as part of a deal with the yamas. After promising to keep a lid on the vengeful spirits that remained there after the yama relocated Hell, the oni were given permission to stay there. As such, many oni, such as Yuugi Hoshiguma, can easily be found partying in the streets here. Suika Ibuki visits here from time to time. Aside from the oni, many other subterranean youkai can probably be found here on occasions, as Yamame Kurodani mentions that the city doesn't turn away visitors.
- Subterranean Animism
The capital first appears on Stage 3 of Subterranean Animism. After Reimu Hakurei or Marisa Kirisame passed Parsee Mizuhashi at the Deep Road to Hell, they'll travel through the streets here. They'll fight fairies and flying yin-yangs will emerge from the distance at the start of the stage. Yuugi Hoshiguma will come and fight the heroines as a midboss, and after a spell card, she'll wander in front of the heroine down the street. She was surprised when she found out that vengeful spirits were leaking out to the above from the Underworld. After she was defeated, she'll point the heroine towards the Palace of the Earth Spirits.
- Double Spoiler
The capital appears in Double Spoiler on stage 6, where Aya Shameimaru and Hatate Himekaidou encounters Yuugi Hoshiguma and Suika Ibuki to try and take photos of their danmaku. The previous stage is at the Palanquin Ship, whilst the next stage is in Makai, above Hokkai. There are 8 scenes total on this stage.
