Actually, no, I take back my words about the food. My Sea Stone theory is connected to the kanji for "Ebi". Of the 4 people who likes lobster, 3 of them use ロブスター katakana. Only one person has lobster written with "ebi", and that's Judge, オマール海老 (Homard lobster).

If I'm super conspiratory, because I suspect that the sea stone might be related to lobsters I would also suspect anyone whose favourite food is lobster. But I'm not at THAT level of conspiracy yet. Though it's also because I'm not 100% certain about the lobster thing anyway.
