Zunda Horizon

Zunko Tohoku has the ability to transform any mochi into zunda mochi by using her Zunda Arrow. She and others, including Kiritan Tohoku, Itako Tohoku, Usagi Chuugoku, Metan Shikoku, and Sora Kyushu, enjoy eating zunda mochi while feeling happy. Chanko Ooedo leads the Natto Factory with Tsurugi Chubu, Shinobi Kansai, Awamo Okinawa, and Meron Hokkaido. Although zunda and natto both use beans, zunda uses edamame, which is harvested before soybeans used in natto. This causes the Natto Factory members to worry about a potential shortage of soybeans. To address this, Chanko sends Awamo and Meron to Zunko's home to eliminate her, but an unexpected third party intervenes.
