On his way to the Black Isotta, Grimm chose to walk to get more exercise, and for this purpose, he walked very fast.
With the mask on his face, Grimm raced on the road, carrying the large sword and also a sack. In it were the heads belonging to three black sorcerers.
"Upon arriving at the academy, how would Peranos reward me for killing three black sorcerers?" Grimm snickered expectantly. "Oh, stop thinking about the reward. I had this wonderful experience and gained knowledge. That's more important."
...
Twenty days later in the Bramble Forest.
At night that day, the lights pouring down from the moon and the stars had been thinned out by the dark clouds. Grimm was sitting atop a giant tree and was feeling the texts in the Devil Pact with his soul using the flash produced by his Flame.
"What magical words! They introduce a way to interpret meaning using souls! They seem to be the natural product of soul waves and might be helpful in learning how to use souls."
