After Dante got knocked out by Baba-Yaga, he slept for a mere half an hour, and during that short time, he had quite a vivid dream.
In this dream, Dante saw himself as a teenager, not older than thirteen years old, standing in an open field where the grass and tree leaves grew purple.
Standing beside Dante, Xander looked at the horizon with his arms crossed, gazing down at his pupil and urging him to "go again."
Right after the teacher spoke, the young Dante raised his palm and aimed at the horizon, where nothing but grass could be seen ahead of him.
With one deep breath, Dante's glare became intense as he seemed to produce a vortex of flames on his hand, shooting out like an arrow that traveled almost 20 meters before dissipating.
"Alright, you are slowly getting the hang of controlling mana," Xander commented with a slight smirk.
"Teacher, what's the point of learning this when I can do something similar with umbra?" Young Dante asked.
