Safety precautions

Since Kaioen's body is basically the biggest turd sandwich to everyone around him ever known, emitting poison from every possible nook and corner and more, some precautions are made to ensure general safety. One such precaution is to always carry around protection suits of sorts, and also a shitloads of antidotes, and as illustrated is to paint his nails with a special polish so as to prevent poisoning from scratches etc. 
My god, he's such a pain in the ass.
