1. He's the Idol Prince.
If you love idols what's better than an idol who also loves idols?! Kengo in fact became an idol himself because he was such a big fan of both female and male idols alike. In particular he likes Sexy Zone who were actually the first male idol group I became interested in myself so they hold a very special place in my heart.
2. He was an odorite.
Once upon a time I used to make Jpop dance cover videos on YouTube. Although that's not something I do anymore, I remember those times fondly and still like to perform on occasion. I was very excited to find out that this is something Kengo used to do too before he became a member of Magipri. In the past he uploaded a few videos of himself dancing to songs from popular idol groups such as AKB48 and Morning Musume.
3. He's very 'otomen'.
It's not uncommon for people to mistake Kengo for a girl what with his soft feminine features, his high voice, and his somewhat girlish interests. This may not be to everyone's taste but I absolutely adore this about him; it was what attracted me to him in the first place. I don't know why but I've always been more into guys who have a rather evident feminine side and even better if they aren't ashamed of it.
