Ryukahr, the alias of a Youtuber and Twitch streamer mostly playing Super Mario games. Ryukahr spelled リュカ (ryuka) in katakana, is the Japanification of the Latin given name Lucas/Luke, stemming from the name Lucius meaning "the bright one" and "the one born at dawn". A common yet incorrect belief is that the name comes from Greek Loukas meaning "man from Lucania", but that is not supported by the evidence at hand.
