Tenshi Hinanawi

Tenshi Hinanawi is the "Eldest Daughter" of the Hinanawi clan that resides in Heaven. Due to the boring life in Heaven of constant drinking and relaxation, Tenshi decides to cause a disaster by gathering the thought energy of everyone in Gensoukyou in the form of scarlet clouds, threatening an earthquake. Her true intent is to resolve her boredom by attracting others to resolve the incident. This disruption causes a preliminary tremor, which wrecks Reimu Hakurei's shrine, causing several events to unfold from there. Eventually, Tenshi rebuilds Reimu's shrine.
