This is a Touhou doujin music video themed around the Secret Sealing Club. It's a masterpiece that depicts the encounter, separation, and reunion of Renko and Merry, set to arrangements by the popular music circles, Diao Ye Zong and Kimi no Bijutsukan. It includes two parts: "Mou Ichido, Mata Koko de.", which directly portrays the sorrowful story of "Zettaiteki Ippoutsuukou" from Diao Ye Zong, and "Mata Koko de, Mou Ichido.", which depicts Renko's determination and obsession against the backdrop of Kimi no Bijutsukan's edgy Greenwich in the sky. I just rewatched it for the first time in a while to check the playback, and it was incredibly interesting. It was stored in a dark place, so the case has no major scratches or dents, but fine scratches can be seen. Please consider this item as a used product and understand its condition before purchasing.
