Inzai Aru Aru Monogatari

A short in which a student named Ai meets an alien with a time machine. Ai also appears in the short "Kobe to Watashi".

OVA based on the manga by Michihara Katsumi.

Yearning to get along with others and not be disliked, first-year high school student Hiiragi finds himself unable to say no whenever someone requests something of him. One summer day, while unsuccessfully carrying out yet another request, he encounters an oni girl named Tsumugi, who has come to the human world to search for her mother. She does whatever she pleases and is the complete opposite of Hiiragi. Snow mysteriously begins to fall... and their adventure begins.

The anime is set in 2045, where the Internet and AI are commonplace even in space, and centers on a group of children stranded in space after a large-scale accident occurs in a space station. By using narrowband, social networking, and a drone that they can manipulate through smartphones and low-intelligence AI, they overcome many crises. Note: Also released in Japan as a 2-part film series with the same content, the first part showing in theaters simultaneously with the worldwide Netflix release.
