IIRC it is indeed a different kanji, but the reading is the exact same. Kinda fun to note that one of Ichitaro's major roles (Dynasty Warriors' Zhong Hui) shares the same kanji as both his stage name and real name. But eh let's not venture further. Still, kinda fun to know where the Ai Ai jokes came from

Also, I just noticed that in the second picture there's an illustration of a girl in a wedding dress along with Ichitaro's trap chara in pso2 who's also in a wedding dress wwww. So does that mean the wife also plays PSO2? Lucky man
