Ohey look who still lives. I'm going to give you a simple one today, just so I don't die waking the blog up after so long. It is actually an oldie (as you can see here), which is why this is so easy.
But what is this really? Well, it's the logo/face of the mascot of the solo singer Piko, who's just as cute as his mascot. Which is a rat by the way, not a cat, however much it looks like it.

This is a picture of the Pikochu plushie toy that is sold as merch. Below you can see the video for Nisoku Hokou, which is a self-duet, perfectly illustrating his ability to sing with both a "female voice" and a "male voice".
