Hamomoru Tachibana, uma clériga séria, acaba se perdendo em uma floresta próxima a um santuário em Kyoto durante um festival noturno do início do século XX. Lá, ela conhece Chuuya Shingoh, um entusiasta da ciência que a apresenta à Bacia de Observação de Estrelas, usada para cultivar objetos celestiais como estrelas. Sem carteira e sem como voltar, ela se junta à pesquisa dele para criar modelos do céu noturno com pedrinhas e testar sua influência na cidade por meio de adivinhação onmyou.
Os jogadores guiam Hamomoru nesta simulação indie de cultivo celestial, criando estrelas na Bacia e explorando as ruas de Kyoto ao lado de Chuuya. O loop principal mistura experimentos na bacia com caminhadas no mundo real para observar os efeitos. Fãs de simulações reflexivas vão curtir o ritmo deliberado e as experimentações místicas.
"The idea of creating a box of jewels, each filled with life... doesn't it give you a little bit of a thrill?"
This Starry Midnight We Make is a celestial growth simulation game wherein the protagonist, Hamomoru Tachibana, creates celestial objects using the mysterious Star-seeing Basin.
Hamomoru Tachibana, our protagonist, is an overly serious, easily-flustered clergywoman. While on vacation in Kyoto, Japan in the early 20th century, she went to visit a night festival at a local shrine. While enjoying one of the local specialties, she found herself lost in a deep forest road near the shrine.
In the depths of the forest, flanked by a trio of archways, Hamomoru meets Chuuya Shingoh, a curious, self-professed student of sciences. Chuuya shows Hamomoru the "Star-seeing Basin", wherein one can seem to "grow" stars and a model of the night sky using pebbles, and invites Hamomoru to join his experiments. She is hesitant at first, but her missing wallet compels her to remain in Kyoto regardless.
Ultimately accepting Chuuya's offer to help with lodging, she agrees to assist him in his "research" in return. According to Chuuya, the stars created in the Basin may be able to influence the rest of the city in a manner similar to what is often described in onmyou divination. To confirm this, Hamomoru and Chuuya shall walk the streets of Kyoto, all while creating stars within the Star-seeing Basin...
