The peaceful monster Houlinga appears and becomes the Sakane village's centrepiece in tourism. One month later, the mayor requests Xio to cure the monster after it was found suffering from malnutrition but as they injected it with a cure, the monster rampages. A little girl name Hana reveals that Houlinga was supposedly to die on the village and becomes a mountain at the end of its life cycle. When Xio members attempt to relocate Houlinga, the monster continues to rampage and sprays pollens until Ultraman X quarantine it and remove the drug launched by Xio, allowing the monster to peacefully end its life cycle.
