Hero Clan
Albareos[]
Both Albareos and Reginleif were allied with one another due to his interest in their cloning project by using DNA from Jin Toujou and assisted in its completion, along with ensuring that the corruption levels remained manageable. However, similar to Ornis, Reginleif viewed humans as mere to them as he went behind the backs of Albareos and the Vatican researchers to turn Shiba into a suitable divine vessel for himself.
Shiba Kyouichi[]
At first, like the other failures, Shiba was originally seen as immaterial until the true extent of his capabilities was discovered. Afterward, Reginleif sought his power to store and convert corruption into power, causing him to view Shiba as nothing more than a tool to make himself stronger while underestimating him. His arrogance would soon lead to his downfall as Shiba was aware of his abilities and instead absorbed Reginleif into himself, turning him into his weapon, while Reginleif gradually vanished inside the abyss within Shiba.
Divine Realm
The relationship between him and others from Ten Gods is unknown but most likely hold him in great regard due to his position and strength.
Afureia[]
Though their exact relationship was unknown, it could be assumed that they were at least good comrades based on the memories Shiba gained after absorbing him along with realizing the nature of Shiba's armguards.
Raphaeline[]
Though their exact relationship was unknown, due to them being among the Ten Gods, they were both comrades of the same ranks. However, he doesn't help her when Raphaeline was judged for unknown reasons, despite that his decision could change her fate.
