RPG WORLD HAD SOCIA MEDI GN 01

When a fantasy world has fully functioning internet and smartphones (for some reason), it's only natural for its sixteen year-old shut-in of a Hero to declare war on the Demon Lord who has kidnapped the kingdom's princess via text message. But is it natural for that Demon Lord to be an innocent snowflake who hates conflict!!? And somehow, this hopelessly weak Level One Hero ends up texting this overly pure Demon Lord, her cheerful Generals (who all adore her), and the princess who also seems to be developing a major crush on her captor as he goes about his adventures!
