Shinen no Kariudo

The protagonist is a young man named Shiki who has run away from both job hunting and studying. He spends his days obsessed with online games, but his selfish behavior leads to his friends abandoning him and him becoming lonely. With a fresh start, he starts a new VR game called "Shinen no Katsubito" and soon encounters a beautiful woman being attacked by a tiger in the game. Shiki risks his life to save her, but... This is a battle fantasy where the virtual and real worlds intersect. (Source: Natalie, translated)
