Touhou Gumonshiki ~ Memorizable Gensokyo

Within the human village of the hidden land of Gensokyo, there exists a clan dedicated to documenting the history of its inhabitants, be they human or youkai. Every 120 to 180 years, a Child of Miare is reborn, carrying with them the memories of all their past lives. However, these children are also cursed with short lifespans, rarely surviving past the age of 30. As the ninth Child of Miare, Hieda no Akyuu is tasked with working on the ninth Gensokyo Chronicle. Yet, she starts to reflect on the nature of her existence—marked by an extensively long memory but a strikingly brief life. Her journey is one of profound contemplation, bridging the vastness of time with the fleeting moments of her lifespan.
