Straightforward tbh. Spiritual essence encompasses one’s concept across all of history. Even if one’s spiritual essence were to completely vanish a divine spirit could enforce their authority to come back. Meaning they can come from material, spiritual, historical, conceptual, and informational (imaginary number) destruction. Right now it would only mean that Izayoi would get High-Godly regeneration negation.
“There are two measurements to indicate the level of the which called [Spiritual Essence] in Little Garden.1st, [Total Mass] in the Material World. The Star Spirits being counted as a Strongest Species is because they were a species stands at the top of this field. The Star Spirits, the perfect lifeforms which are amalgams of Material Physique (Material), Stellar Physique (Astral) and Imaginary Number Physique (Tachyon), are considered to be extremely powerful among the Three Great Strongest Species.2nd, the [Density of Time]. The higher for existing time of a [Spiritual Essence] from its materialization to the present, its possibilities of manifestation and its density of existence in parallel universes, the mightier and brighter a [Spiritual Essence].”
”Then Divine Spirits are the Strongest Species that dominates Spiritual Essences of era and concept.”
”"Perseus" is a knight that was described by Greek Mythology that was written on BCE. If that "Perseus" had his Spiritual Essence (Existence) deteriorated, there is a possibility that the influence of the Greek Mythology on the future generations is dropping rapidly. At worst, even there is a chance it being annihilated completely. However, since the influence of the Greek mythology to the future worlds, becomes wedge on large-scale "Historical Transition Period" such as philosophy, sect, political,...... they will emerge on all time axes in one form or another regardless whether their stories and fables exist or nonexistent. Therefore, superficial method isn't enough to kill beings ascended to Divine Spirits from belief. As mentioned before, since the Divine Spirits are lore of the stars, their Spiritual Essence can resurrect by the enforcing power which maintains their lore.”
