Your video offered me a further view into the ture ending, heartfelt thanks.
Nonetheless, the 4th circumstance is nearly cruel XD, player barely remain any money before the boss battle, while the only way to Rinnosuke‘s shop was "a quarter of million yen". I did met Ruukoto and Rock(at the first sight of each five crystals I sensed they could served as clues for the questions following), even visit Kosuzu with Reimu(and she offered some help iirc), and failed the final condition, what a pity(though I then learnt the right manner from ur video)
Anyway, thanks for ur hard work, not only for reply but also for the video you made♪(´▽｀)
