[Suigetsu X Kaito] Messages from the Future

Not long after joining the Demon Slayer Corps, Inadama Kaigaku found a black box while out hunting demons. By chance, he opened it and saw a message that had arrived just then.

Sender unknown. Recipient unknown.

It looked like nothing more than a billing notice, but Kaigaku couldn't understand a word of it. Then he reached the final line. It was completely different from everything before it. He recognized every word, but put together, they still made no sense to him.

"Good day--

I'll be waiting for you in the future."
