The Japanese editions of Love Live! School Idol Festival: ALL STARS and, now, Love Live! School Idol Festival 2, have featured daily skits starring two or more idols across the generations. These skits provide a huge amount of interactions and character development, but they're not available in the World edition. To fix this, @SIFAStheatre has been translating and posting these for the English-speaking community.
Reading through the collected episodes, I found myself wanting to be able to quickly jump to episodes featuring specific idols, or which mention specific characters. I also found myself wondering: which idols appear together the most? Which idols mention each other in conversation? So in a fit of fanac, I assembled a database indexing all these things, and offer this website for Love Live fans who harbor the same questions.
Be sure to look at Statistics and Patterns in the data.
Keyboard navigation On the episode display, you can use the forward and back arrow keys to move to the previous or next episode; the [A] and [D] keys also work (as in the WASD direction keys games often use). Jump to the [F]irst or [L]atest episode, or use  and  for the same thing. There are also keyboard shortcuts for the main navigation icons: [S]earch, [L]atest, [R]andom, and S[t]ats.
