@ Taka

I found the rawscan for Chapter 264: http://yesmanga.net/sket-dance/sket-dance-chapter-264/5827-mangaraw.html?Page

In this chapter (which the setting is in the summer), Switch turned in a postcard for a mascot idea for a company. The mascot idea was approved, but for the mascot to have a good rating, the mascot has to have human characteristics and write blogs. So, one person is chosen to dress up as the mascot and spread its popularity. The person chosen was Bossun.

So "Mascot Summer" would work for chapter 264.

The literal translation for chapter 265 is "Retirement Game", but "Last Match" sounds nice for chapter 265.

For chapter 274, I think "Student Council's Disassmebled Cake Incident" might work better. The cake wasn't smashed, but the Student Council tries to recreate the cake that they ate. They each draw a piece of the cake they ate and tries to fit the pieces together in order to recreate the cake.

Hopefully I was helpful!!
