This is a representation of a scene in a dream I had. Essentially, an ancient alchemist discovered an elixir, called Substance AAAAAA, which was the key to eternal life. Substance AAAAAA gives you immortal life, but the downside is that you transform into a werewolf and are forced to kill from time to time. The secret of making substance AAAAAA was thought lost by the royal family because the alchemist died with his secret, yet a faithful monk, who dedicated his entire life to this alchemist, was entrusted with the secret. Apparently the monk and the recipe were then stolen by Charles Darwin in his Beagle Battlefleet, because werewolves and evolution, duh.

This child prodigy scientist was experimenting with Substance AAAAAA, and gave it to five test subjects. As he notes in the dream while describing the situation to me:
"I gave Substance AAAAAA to five individuals. And what happens with people who inject Substance A is the same. They'll grow taller, their hair will grow blond and their eyes will go silver. They will gain these urges to kill, to consume human flesh. I gave this to five individuals, and then they transformed into hungry werewolves in front of me, surrounding me and one lifted me up to eat me"
What happened was these people did not appreciate being turned into werewolves, and were about to take out their revenge on the child scientist. Who then transformed into a werewolf himself and was like "please don't kill me, I'm a werewolf too" as he was being lifted up by his lab coat. Apparently he'd been a werewolf for a long time, and had killed, in secret, a great many people. Not so innocent and childlike anymore!
Although the other werewolve's expressions and drawing style are rough estimations, the position of the child scientist, expression, and body shape are exactly how I pictured him in the dream. He was a super adorable werewolf kid
