I decided to lump the colour pages in with the first chapter for this week’s reading, though it does make for a little bit of a monster reading. You’ll be fine. In any case, chapter fourteen corresponds with episode nine of the anime, while chapter fifteen is the first half of episode ten.
Chapter fourteen’s title image is from Yakousei no Ikimono Sanbiki by Yura Yura Teikoku
For chapter fifteen’s, though, I’ve got nothing.
Bocchi’s general behaviour on page 10 is entirely perplexing, though I suspect it’s meant to be, and I’ve been entirely unable to determine whether any of what she’s doing, including the cicada graves, is some manner of stereotype. Astaxanthin and canthaxanthin are both naturally-produced red pigments - the former is the reason why lobsters and prawns and so forth turn red when cooked.
Page 11, docosahexanoic acid (DHA) and eicosapentaenoic acid (EPA) are both omega-3 fatty acids, and important components of the human brain. It’s probably well-known enough that you don’t need me to point it out, but Enoshima is here - as Kita mentions, you can get there on the Odakyu line from Shimo-Kitazawa. Shirasu-don (whitebait on rice) is a well-known specialty of Enoshima (and also Kamakura and Chigasaki).
Page 12, the manga doesn’t show it, but in the anime, they’re emerging from Katase-Enoshima Station in the first strip. In the second strip, the manga (again) doesn’t show it, but in the anime, they’re buying the takosen from Asahi Honten.
Page 13, the first panel depicts the Grand Torii of Enoshima Shrine - they ride the Escar instead of climbing. Page 14, they’re somewhere around, uh… here, then they visit the Sea Candle.
Page 15, Bocchi’s pose in the top-left panel is, of course, Yamcha’s death pose.
And after that tidal wave of locations, chapter 15 is much more sedate. They’re at school. And the club. Though there’s a couple of visual puns in the anime that aren’t in the manga, which I’m sure people can spot.
