A mysterious atmosphere had recently enveloped the Heaven Realm, becoming more apparent since the return of the Celestial Clan's Emperor. Particularly alarming was the evidence suggesting that the Emperor was frequently in contact with the renowned warlike race of Okaman, seemingly having signed a troubling agreement with them. Consequently, more Okaman have been spotted within the territory of the Celestial Clan, causing unease among the residents. After all, the reputation of the Okamans as war fanatics was not unfounded. Following the great war between the three realms, a peace agreement had been established, with the Celestial Clan aiding the Okaman with technology and funding for better living conditions, in return for the Okaman's promise not to interfere with the interests of the Celestial Clan.
