Keiki Haniyasushin is one of the two main antagonists and the final boss of Wily Beast and Weakest Creature. She is a deity summoned by the human spirits of the Animal Realm to protect them against the animal spirits, leading her to slowly take over the Animal Realm and drive the beast spirits to begin plotting to invade Gensokyo.
History[]
Within the Animal Realm, the human spirits were subjugated by the four powerful beast spirit families, who herded them into the Primate Spirit Garden for the beast spirits to continually prey on them. This led the human spirits to come together and prey for a savior, resulting in them summoning Keiki. Keiki began building an army of haniwa idols, led by Mayumi Joutouguu, and used them to occupy the Primate Spirit Garden and begin a slow takeover of the Animal Realm. As a result, the beast spirit families formed a temporary alliance against Keiki and began plotting an invasion of Gensokyo.
News of the animal spirits' invasion soon reached Reimu, Marisa and Youmu, who set off for the Animal Realm to stop the invasion. As it turned out, this was all part of the plan of Yachie Kicchou, the head of the Kiketsu Family, to draw in a flesh and blood human who could defeat Keiki's forces. After defeating Mayumi, Reimu, Marisa and Youmu go on to confront Keiki and defeat her, putting a stop to her advance on the Animal Realm, although the humans still remained under her protection.
