Raibaru Fumetsu

Best friend and bodyguard: Raibaru is Osana's loyal and protective best friend, accompanying her for most of the school day. Her constant presence makes it nearly impossible for the player to directly attack Osana, which is why she is often described as a "human shield". Former Martial Arts Club president: She is a highly skilled fighter, having previously served as the president of the Martial Arts Club. Students gave her the nickname "The Indestructible Rival" due to her perfect winning record against anyone who challenged her. Formidable opponent: As a "Protective" persona, Raibaru will not hesitate to apprehend the player, Ayano Aishi, if she witnesses a murder or assault. She is powerful enough to instantly incapacitate Ayano, leading to a "Game Over". Character development: The original iteration of Raibaru was heavily criticized by fans for being an "unbeatable" character that ignored most of the game's mechanics. In 2021, Raibaru Fumetsu is a character from the video game Yandere Simulator. She is the best friend of Osana Najimi, the first rival of the protagonist. Her name, "Raibaru Fumetsu," is a combination of the Japanese word for "rival" and "indestructible," reflecting her in-game role as a formidable obstacle to the player.
