Natsunagu!

Natsuna Keyaki abruptly lost communication with Itsuki, her closest online friend, after earthquakes struck the Kumamoto Prefecture. Natsuna sets out to find her from Tokyo to Kumamoto with only a sketch of the surrounding area. In the disaster-stricken prefecture's rural areas, Natsuna becomes lost and meets Izumi Chiba, an animated middle school student, and a police officer. Izumi offers Natsuna shelter and information to help her in her search, along with her kind family members. Natsuna advances toward learning what happened to Itsuki with the assistance of these nice locals.
