As for going on a shopping spree, it sounded nice, but he should probably get back to work soon. Money made it so that he had more opportunities to read and gather information once he left the Academy, but the library pass was still useful and a valuable resource he might not be able to find elsewhere on the continent. While he was here, it was better if he devoted most of his efforts there.
As for shopping, practicing with the formation plates he had just bought, and the rest… it would have to be on his next 'break.'
Thus, after thinking for a moment, Di Toou threw the remaining Spirit Stones and the random items for creating formations into the sleeve on his left arm, and the two extra robes alongside his old rags and the kept pieces of wax paper into the bag on his right sleeve.
As for the newly bought brooms…
They were stored in the fourth bag he wouldn't be bringing out with him.
