Tsutaou

Nozaki Sumire is a little bit "dry" for a high school student, but the truth is that she's just bad at relationships. Suddenly, a huge explosion occurred and she's engulfed in a fire!

All of a sudden, she appears in front of a good-looking man with silver hair and purple eyes! Is this the identity of Gladitoria's former emperor?! (Or- What is the identity of the silver-haired man?!) Furthermore, the mysterious sentient ivy serving him. In the cruel emperor's era. A love story revolving around two people in a gentle fantasy world!
