You and your friend, Aether, were told to clean up the chemistry lab after class.

And it so happened that Aether accidentally tripped over a test tube that appears to be left on the floor―crashing against a table, and covering himself in a mixture of weird substances.

As you heard the shattering of glass, you approached him quickly―genuinely concerned.

"Ow..." He mutters, glancing around.

Wait, something is wrong―why does he suddenly have a tail and cat ears?!
