In reality, "Dr. Daisuke Kaito" may be Nigerian scammer living in a household with his darling pets, some big and fat but stupid crocodiles. In reality, he is definitely in need of any teachers because the foreign language that his nasty crocs are able to learn would not be one that you could really teach!

So, don't send him anything, his crocs are definitely illiterate and therefore would not know to appreciate your application efforts...LOL
