This era is ironically named, as “Heian” can translate to “peace”, and the period was named after the Japanese capital at the time, Heian-KyÅ , known to us in the modern-day as KyÅ to.
In a world under the menace of a ghost, who will you end up falling for...? This is the Heian period. Our protagonist would rather be strong than feminine, and thus she's trated like a weirdo.
