For the record, this is one of the cutest, funniest stories I've found in this fandom. Every chapter is a joy. The basic gist is that the antidote's reaction gave Shinichi a Healing Factor, and the combination of Shinichi still using super strength shoes, Snake accidentally sniping the wrong person at a KID heist, and Shinichi following that up with a very poor choice of words leads to the Kaitou KID taskforce becoming utterly convinced that Shinichi's a vampire. In order to cover up the existence of APTX 4869 and prevent anyone from connecting his unique medical condition with Haibara, Shinichi decides to go with that, and (together with Kaito, Haibara, and Agasa) thereafter conspires to troll the entire police force. Somehow, this is all entirely in-character—Kaito's just a really bad influence.

Cue an adorable Slice of Life-style comedy with a tad bit of romance sprinkled in, filled with a surprising amount of Reality Ensues and medical conditions bordering on Sufficiently Analyzed Magic.
