Touken Ranbu Mikazuki Munechika x Yamaba Kiri Kunuhiro, I bought the official puzzle of Sanzan before, and then I said that I would put the puzzle together this weekend and finish writing this idea, it almost became a flag 2333. A short story about a blue whale and a canary, but the writing and the plot are worrisome. Although QAQ said that it had checked some information, there are still many unscientific parts. I am very sorry.
Well, thank you for reading and please point out any deficiencies.
