Tamaki revealed her criteria for a husband years ago
1. Has looks similar to her favorite actor. (Handsome)
2. Height over 180cm (average Japanese height is 170cm, so probably in the top 15th percentile or so, basically tall)
3. Within 5 years of her age (Relatively young)
4. Makes more money than her (She's one of the most successful indie tubers + a popular artist)
5. "A guy who'll be like a mom to me" (Basically pampers her)
This is basically what every chuubas want to marry. And btw 6. is that he shouldn't be a fan or her nor an otaku
