"Mirai!" Belladine flew toward her. "Mirai! Mirai! Please save Master!"
"Eh?" Mirai's eyes widened. "Ah, you must be Louis's Familiars…! So you're safe! Ugh… this must be his Domain? His Heart?"
"It has grown twisted and is no longer physical," Niflheim explained, floating in front of her. "This entire place has become a Fantasy Field, slowly evolving into a Fantasy Domain—a separate, physical dimension where Louis, now a Grievance, would rule."
"S-So it's the same as with The Gardener then," Mirai said, standing slowly with Niflheim's help. "You're…! Wait, aren't you Tisha's sword?"
"It would be complicated to explain, but yes, I am Niflheim," the frost blade replied. "Just not from this world… or rather, this timeline."
"From the previous?!" Mirai was amazed. "S-So Louis can bring along such things? He can bring consciousness and bonded spirits?"
"I'm not sure what the limitations are," Niflheim sighed.
