The Place Promised in Our Early Days

In an alternate-reality 1974 Japan, the country is split, with the southern islands controlled by America and the northern lands claimed by the Soviet Union. Hokkaido, referred to as Ezo in Kumo no Mukou Yakusoku no Basho, decides to construct a tower into the sky designed by Ekusun Tsukinoe. By 1996, Hokkaido Tower's construction is complete and three students of Aomori have big dreams concerning this tower. Hiroki Fujisawa and Takuya Shirakawa are considered child prodigies, and both harbor romantic feelings for Sayuri Sawatari, though neither of them would dare admit it.
