Hello World
Set in Kyoto 2027, the Japanese government has made plans to collect and preserve the city's natural architecture and culture through drones in real time, storing all its data in an infinite-capacity machine known as Alltale. Naomi Katagaki is an indecisive high school student living in Kyoto who harbours a love for reading. One day after school, a mysterious yatagarasu steals his library book and in an attempt to get it back, he meets a strange man that appears out of nowhere. This man, whom only Naomi can see, is revealed to be himself from 10 years later, now grown up and an adult. The adult Naomi explains that he has accessed Alltale from the real world outside in order to change the recorded past and save Naomi's to-be girlfriend, his classmate Ruri Ichigyō, after she was unfortunately struck by lightning at a fireworks festival and rendered comatose. The teenage Naomi decides to call his adult self 'Sensei' and agrees to help, as his adult self has limited capabilities as an avatar within Alltale. Sensei then gifts Naomi a special power, God's Hand, which manifests from the yatagarasu as a translucent gloved hand, to allow him to create anything as long as its chemical and physical structure is not overly complex.
