Hello! My name is Kai Hirasawa. I'm married to Yui Hirasawa and I live in Toyosato, Shiga along with Ui and her parents, Masaoki and Sayoko. I work at a visitor information centre in a nearby town called Hikone. I was born on February 18, 1991, as Kai Watanabe. Why did I change my surname, I hear you say? Well, it's because Yui doesn't have any brothers, so because of that, I had to take my wife's surname when I got married. I'm completely fine with it, given my childhood circumstances.

Here are a few things I love to do. Firstly, I love to help tourists when they're travelling around Hikone. I speak very fluent English (in a British/Australian accent, to the surprise of others) and Chinese (Mandarin and Cantonese). We don't get that many foreign tourists around here, so I'm always willing to help them out. Usually, I have to give them a brochure on Hikone Castle since it's the nearest tourist attraction. There's at least two or three of us at any given day. I work part-time three days a week, plus casual work on other days if they call me.

Secondly, I'm a part-time vocalist for Yui's band, Ho-kago Tea Time. I'm the one who usually sings the Chinese songs in the band. When we post videos of us playing songs in Chinese, it usually says Ho-kago Tea Time feat. Kai. We've done a few covers, plus I've written a couple of original Chinese songs (with the help of Mugi and Philip). I've sung a couple of duets with Yui as well and we're thinking of doing a collab with Azusa's band, Wakaba Girls.

I remember this time when the band worked with Flumpool, and China Blue along with Philip and a couple of guys from New Zealand (who also used to work with Philip). The song was called Belief and it was for a movie called Oshin. Philip was one of the guys who was on lead vocals, while Mio and Yui did some backing vocals. If you listen carefully, you might be able to hear them.

Yui still hangs out with her friends from time to time. Sometimes she takes me along as well, whether it's just lunch nearby, or a shopping trip to the city. Well, at least Yui lets me free while she goes shopping, but by the time we have to go home, I'm usually the one to carry all the shopping!

Thirdly, one of my "secret" hobbies is, dare I say it, bedtime fun with Yui. In bed, all bets are off, or literally, everything is off. You see, there are two reasons why I like this. Firstly, it's what couples do. Secondly, the Doctor told me to have as much fun with her as I could. Apparently, he saw a future that involved Yui getting into show business. In that future, Yui was very sleazy. She had sex with anyone and took drugs. She eventually died of a drug overdose. The Doctor warned me not to let Yui go into show business and to let Yui release her sex drive on me. Well, the Doctor didn't say it like that. When he told me, it took me about 90 minutes to realise what he was talking about. Right at that point, I said, "Oh, I see!"

Yui replied, "See what?"

Have we ever thought about having kids? Well, no. We decided not to have kids for a few reasons. Well, mainly one. I don't think Yui would be a good mother, considering how she is. Anyway, we can't have babies anyway. An incident a couple of years ago led to us being rendered infertile. I'm not that sure how that happened, but whatever happened, I know it was bad. However, while I do remember being kidnapped and taken to a dungeon, I somehow remember how Yui and I were kidnapped in the first place.
