This is what was missing at the start of the manga. Interaction with more than one female at the same time. Not only Shiori ignores Keima (apparently because of the Kanon business) but now she also witness a shocking scene with Yui.
I knew Yui was going to appear on this chapter. She wasn't hard to recognize on page 9 after Keima began to follow Shiori.
Shiori's silent reaction was as cute as ever.
Who's Yuki?
