The newbies start the chapter at Michi-no-Eki Fujikawa (which is adjacent to the Masuho interchange, so I guess that’s where the name for it in the manga comes from). The first panel specifically is drawn standing a few metres to the east of here (if you turn the camera around, you can see the line of bollards that’s in the foreground of the panel). Here is the website of the bicycle rental company that’s located there. Looks like the last rental time is 3pm, though, so they wouldn’t have been able to just drop by after school in the real world.
The bear featured on the title page is a tanuki in real life (and he’s not shouldering a bicycle, though he is named チャリたぬ). Room with bikes. Shimarin dango.
Wait, the title of this chapter literally just came up in another thread. How very Baader-Meinhof…
On page 85, it looks like they do the test ride in Fujikawa Water Park, which is adjacent. Picnic bench (note you can see the Michi-no-Eki peeking over the hill in both this photo and the manga on page 86).
Then we’re back at school on page 88, back here 94, at Mei’s house on 95 (eventually I’ll get enough clues to locate it. Maybe it’s within walking distance of the Michi-no-Eki? Though I feel like she wouldn’t be riding the bike to school if it were) and then back at school again on 97, where they remain.
Page 87, I rather suspect someone is in the wrong gear. When did this manga become ゆるサイクル, though?
Page 93, you can see their firewood collection from a few volumes ago in the background of the second-to-last panel. Nice callback, there.
Page 99, Did they get Toba-sensei’s approval for this pizza party at any point? And the interactions between the new pair and the main characters continue to increase…
Page 104, Rin getting weirdly cartoonish again. Surely there are more manga-ish ways to have Rin express shock than having her eyes bug out of her head. Are we gonna see what shocked Ema so much, though?
