Rib (りぶ) is an utaite with a powerful and slightly nasal yet smooth voice which is often described as "kakkokawaii" (cute yet cool) by fans. He can hit fairly high notes with ease.
He sings songs in a variety of genres changing his tone to fit the song. For rockish songs like "Nibyokan" he can put an uncharacteristic amount of power in his vocals, while for ballads like "crystal mic" he sings in a smooth voice that is more emotional and soothing.
He has a distinct and rich vibrato, which his fans have dubbed "Ribrato" (りぶラート), a portmanteau of "Rib" and "vibrato".
He first started uploading in 2010 with a cover of "Marygold" which had 191K views as of October 2016. However, he gained popularity with his covers of "Pierrot" (615K views) and "Babylon" (833K views). His main breakout cover was "Envy Catwalk", which had over 3 million views as of January 2016.
He can play the guitar, as seen in his cover of "crystal mic", which he also arranged.
He can play the piano, and has accompanied his singing various times in namahousous. He often covers songs in his namahousou(s) with either the piano or the guitar.
During a namahousou, he was asked if it was true that he was an ikemen. He replied that it was a lie.
He likes to watch anime that are "comforting", rather than deep, complex anime. Meaning that he likes to watch those that just have cute girls.
He thinks it's embarrassing to give up his seat, so he just pretends to get off and move to another compartment.
According to Soraru and Tentoumushi, Rib is quite amusing when drunk. They say he would sing "Nyaa!" and take off his socks; he'd also crash into a wall and then apologize to it.
Despite seemingly inactive in uploading covers, leading some fans to think he stopped, he is active every now and then on twitter.
He recently returned to twitter after 70 days, claiming he hadn't been able to see tweetbot, having fixed his problem, he once again became inactive. He came back to Twitter for his birthday and said that he's going to continue being inactive and wishes everyone to support him, only if they can.
