What's the name of the song playing in Seto No Hanayome episode 24 at around 15:13? Here is the scene where the song in question is playing.

The clip is taken at around 15:13 into episode 24, at the scene where Hideyoshi Sarutobi slapped Mikawa Kai to calm him down.

Thank you in advance.
That would be Surechigai, as composed by Takanashi Yasuharu

It was included in the Seto no Hanayome Vol.3 - Bonus BGM OST 2 album as the 8th track. 

Several of set-no-hanayome's albums are for sale on amazon So you most likely will be able to find it on there as well.
