Tobitake Tonbo smiled without disturbing Kisame and Samehada's fusion.
However, his senses remained fixed on him the entire time.
After the fusion, Kisame and Samehada underwent a chemical reaction, amplifying chakra in a manner akin to 1+1=3.

"Perfect. I only just finished refining this move, and the range at which it can gather information can't be too great yet!"
The Heart of Steel within him was running, and so was his mind.
