I think Shūkaigami, Chichigami, and Ketsugami possibly work in the similar way the Hindu Trinity do, being the three most powerful Gods in the different dimension that guard its existence. Plus, Melvazoa already does its thing similar like Trihexa but more intelligent (having created its own army instead of artificially cultivating them by external force), so I doubt the three will clash to each other :D.
