You haven’t seen Pitaya Dragon in a while. But during that time period, cookies have been going missing.

You were afraid if Pitaya Dragon was missing. So you checked his cottage. Knock knock.

“…Hm~?”

He said,hungry for cookies but trying his best to resist.

He opened the door with a mask on to prevent trying to bite you or eat you. It turned out that an experiment gone wrong turns him into a jam-drinking vampire.
