Bishamon expected that he will become ayakashi. Before he turned into an ayakashi,she agreed that she will say his real name before he can turn into an ayakashi.
"Kazuma,your real name is...
...
Kazu Yosuke."
And suddenly,his face turned into nothing as if he was dreaming.
He saw it.
His memories of his past life.
He died because he saved his younger sister from an accident. While Bishamon noticed that he's turning into an ayakashi,she rushed into her regalias to equip them.
"Did I save her? Did the truck stopped moving?"he thought.
While Kazuma's body is turning into an ayakashi,some of Bishamon's regalias locked him up in the borderlines.
"Kazuma! Don't get affected by your past! You have a new life now! You have us!"Bishamon shouted.
He can barely heard her but his mind is confused.
"What am I gonna do? Do I still have a place on Veena after being an ayakashi?"Kazuma thought.
"Kazuma! Don't forget about us! Don't forget your family just because you died too early!"She said.
"No! You don't get it...I-I'm just makin you lonely...I...just want to end this!"Kazuma said while crying.
"You don't get it,Kazuma! You just don't know how you make me happy every time!"Bishamon said.
And his name vanished into thin air and turned into an ayakashi.
Before the ayakashi can even break the borderlines,
"Kazuma! I know your still here! Kazuma,come back to us!"She shouted.
And his name was in his hands again,shining brightly like a star.
She felt it. His name in hers.
While Kazuma is turning back into human form but the ayakashi influence is still in there,
"Come,Chouki!" She said.
Instead of changing into an earring and slipping into her earlobe,his soul slipped into his body and become one with Bishamon's body while transforming into a set of garments,a pair of earrings,and a boots with wings((I thought it'll be nice if I fuse Noragami and Grav-Shoes from Ao no Kanata no Four Rhythm.) behind it.(Kazuma can grasp everything,so I decided that he can let someone fly in the air.) In her mind,she saw Kazuma's soul with hers.
"Kazuma,this is...
a 3rd evolution of a regalia's form."She said.
"Is this because of my love for you is too much? And you handled to bring my soul back in the borderlines."Kazuma said.
"I still don't know. I don't heard of regalias having a 3rd evolution. Let's ask Yato about this later."She said.
"Hai!"
