VRMMO De Boku No Imoto to Kanojo Ga Shurabadesu 1 (Monster Bunko) [Light Novel]

[Machine Translation] In reality, Otori Shiro is a dull high school boy with few friends and no girlfriend. In a VRMMO game, he is surrounded by his friends as a strong player Shirou, and he also has a "girlfriend". However, his life in real life changes when he finds out that his "girlfriend", a beautiful girl (*Super Yandere), and Shiro are classmates in real life. The younger sister Asuka, who used to call Shiro "creepy," becomes interested in VRMMO games when she learns that in games it is possible for siblings to fall in love and even get married... A slightly extreme romantic-comedy fantasy from the web, with scenes of love and violence both in the game and in real life!
