An Office, a flask, and many books
The basement of the Oukiwa Academy of Nobles was one of the busiest places in the entire institution and one of the safest. While the external buildings usually had no more than one or two floors, the basement of the primary school building had five floors.
Within this ample space were several rooms for different disciplines, such as Advanced Potion Manufacturing, Alchemy, Cadaveric Medicine, and, for some reason, Business Administration.
After Luke snooped around the gossip of two female teachers talking about professor Vinigo, he discovered that the office of the respected Alchemy Professor was located on one of these five floors. There was a rumor that Vinigo was sick and hadn't left his office for several days.
The half-wolf was very surprised and happy to find clues so quickly without even looking for them.
