Love Angel Syndrome

Yuuna, our protagonist and mentally ill NEET, spends most of her days browsing forums about her favorite anime, Ai no Uta ★ Tenshi Senshi 𝄞. One day she stumbles across an ad claiming to have a desktop assistant modeled after Ai, the main character of Ai no Uta.

Unable to resist the allure of talking with her favorite character, Yuuna downloads the program. Ai-chan turns out to be the girlfriend Yuuna’s always dreamed of– but can a relationship with no boundaries really flourish? Can an AI program actually feel real human love?
