189 'Fire God Kagura

"Long time no see, Mr. Tsukiguni!"

Excitedly, Tanjirou greeted Reiger.

"Hello." Reiger nodded at Tanjirou, saying, "It has indeed been a long time."

When Reiger was first hosted by the Rengoku family, he and Tanjirou used to meet frequently, but since Reiger began developing an entirely new breathing technique, attempting to evolve the Sun Breathing, he hadn't seen much of Tanjirou.

Tanjirou did often come to see what Reiger was up to when he was working on evolving the breathing techniques, but by then Reiger had devoted his entire being to trying out the new methods, neither seeing Tanjirou nor greeting him.

And after Reiger completed the evolution of the Sun Breathing, Tanjirou had left on a mission and wasn't at headquarters.

So, counting carefully, the two hadn't seen each other for at least one or two months, which could justifiably be called a long time.
