Recluse Mahiro would rather lose himself in his video games than venture into the outside world. After emerging from his cocoon of a room, he’s shocked to see a teenage girl staring back at him in the mirror. What did his younger sister Mihari do to him? Mahiro should be angry, yet he’s curious about this second chance at life. Can he soar in this brave new world? He’s intrigued to find out! (Source: Crunchyroll)
