References include:

The barista handing Nakamura a tray with Short Circuit-kun and a smiley packet (presumably of tranquilizer, as in no 56; Short Circuit-kun also plays a prominent role in no 61)

Fey henchman "Funny" 13's cap in the display case (no 57)

A passed-out Nakanojo (likely no 61)

Three boxes of karuta [a card game] on the scale (no 63)

A piece of paper in the display case with the number 80 written on it and underlined (most of Shorts 5, where Yuuko scores an 80)

-The sign in front seems to read "hatijyu tten" or similar. Is this something?

A baseball on Yuuko's tray (likely referencing Invincible Alien from Shorts 5)

Two Go pieces on the scale (no 58)

[Tenative: On the sign on Mio's tray, it it kind of looks like a high jump from no 59. Maybe.)

Mai with a crow (no 66 at least; I remember a chapter where, in the backkground, Mai is hanging out with a bunch of crows behind the school, which is referenced in the anime version of no 66.5, but I can't find it.)

The barista and Daiku cafe (no 67)

A small sign with an umbrella and what looks like Hakase's frog overcoat (no 68)

Yuuko's wallet (no 71)

The one-eyed daruma (no 72)

There's also what looks like bread in the display case with a sign that looks like it says "oneisan", but ?
