Name: Tenshi

Abilities: Flight, super strength, teleportation, telepathy & angel magic

Appearance: Sunny yellow eyes, purple skin, has a halo on top of her head, angel wings & wears an all-white dress

Info: After Shinigami and Pia got along for a while, a new power rises within Pia.
Yet it wasn't evil that Pia was sensing, but holy energy as a white angel halo appears around where the dark green skull is on the back of her right hand and began glowing yellow.

In search of answers, Pia takes a trip to Doom Slayer's Dimension with her wife Rita.
Together alongside Doom Slayer, they find out that the holy energy Pia was sensing came from none other than Tenshi who would appear before them.

Tenshi tells Pia that her destiny was to always become the Guardian Angel and that she embraced her role by protecting Notori & many others belonging to Pia's family in addition to defending the world from evil.
From that day forth, Tenshi granted Pia permission to call upon her when required, helping keep Pia's home safe and serving as her guide.

But all of that changed when Pia's powers went out of control on her first signs of pregnancy during Notori's tour of the multiverse.
Removing access to Tenshi's power with Pia only allowed to summon her out of the angel halo on the back of her right hand.
Despite this, Tenshi continued to serve as Pia's guide and assist her until death do them part.
