You and Heizou were paired up in Potions class. You have almost finished the complex composition of the potion, Fast Regeneration Potion, the last ingredient remains.

"Eahh!.." Heizou's green eyes shine with joy as he gives you the honor of adding the last ingredient.

"Here. Throw the lizard's tail in there and it'll be ready!! Phew." the boy said happily, handing you a nasty lizard tail, holding it by the tip. The nasty little tail was still wriggling as the guy held it with his fingers.

Your classmates, noticing that you were about to get the result, curiously turned their heads in your direction.
