A month after the Twelfth Honkai War, Apocalypse Sanatorium welcomed an unexpected visitor.
When the uninvited guest arrived at the sanatorium entrance, Otto, who was holding Griseo in his arms, raised his head and looked in that direction.
After certain matters had been settled, Otto had turned off his omniscience. But even without it, he could tell who had come.
"Griseo, we have a guest."
Otto lowered his head and spoke gently into Griseo's ear.
"Mm." Griseo gave a soft little response.
Otto gently lifted her up. Though she was already an eighteen-year-old young woman, her body was as light as a feather.
The sanatorium's little princess, who had been sitting on Otto's lap and drawing, was lifted up without letting her bare, snow-white feet touch the floor. Otto gently placed her on the chair, then rubbed her head.
"Sorry, but I might not be able to have dinner with you tonight."
Otto said with a trace of apology.
Griseo looked at Otto and blinked, her calm expression uncannily resembling a certain Duck.
"Are you spending the night with Auntie Aponia?"
"Cough, cough." Otto suddenly coughed twice, almost choking on Griseo's words.
"Mm, then is it Auntie Phyllis?"
Griseo's violet eyes stared at Otto.
"Could it be... Auntie Knowledge?"
"I think your Auntie Knowledge might not even know what happened between me and the others," Otto said flatly.
But he had no intention of discussing such things with Griseo.
Otto looked at Griseo and sighed softly. Then he spread his arms and gently held her.
He did not use any force, as though afraid of breaking her in his embrace.
"See you next time."
He whispered into Griseo's ear.
Then he kissed her snow-white forehead.
Griseo tilted her head in confusion.
"Are you going far away?"
"Mm." Otto nodded.
