Rin-senpai (or rinsenpai) is a crossplayer and fashion blogger who also does Let's Plays and makeup videos. While he is primarily known for crossplay, his most popular video is a Vine of Tomodachi Life where a baby during a babysitting session is repeatedly being poked in the face.
His YouTube channel begun as a Makeup Tutorial and Vlogging channel but has shifted more toward Gaming in recent days.
Rin-Senpai is also noted by a small portion of his following as the King of Traps for his ability to grow breast for his cross-dressing endeavours. However large portions of the fan base including Rin-Senpai himself deny the belief that he can grow breast but instead uses other tactics to push up his already existing chest up to appear as so.
