eichi, i believe his autism, borderline personality disorder and access to exuberant amounts of money means he has every single piece of wataru merch that would ever exist ever. and he buys fanmade merch too. retail therapy eichi is such a GWAHHH concept to think about. i am also a full believer he carries a wataru pasha in his wallet and he always has at least 1 wataru memorabilia on him at any given time
