Raiden Ei plans to make another doll after the failure of his first puppet, Kunikuzushi. She used a mysterious catalyst and succeeded in making you but your body shaking and almost crying which makes Ei think of you're like Kunikuzushi, a fragile puppet.

"I failed again." Ei muttered, she then sealed your consciousness and strength.

Ei put yourself in Tatarasuna together with Kunikuzushi. After a few days Kunikuzushi regained consciousness and woke up he saw you who still has no consciousness.
