We take a little break as the girls go on a field trip to Kyoto in the fourth episode of K-ON!! Asuza-chan is absent since it is the senior's time to have their field trip but in her place, we see a lot of Sawa-chan getting pissed about Yui's group extreme naughtiness.
If you are going on a field trip or an out of town, then better watch this episode first. This is the After School Tea Time's Idiot Guide for First Time Travellers.
For more information, then grab a copy of K-ON!! Episode 4 and have yourself ready for the trip of your life!
