The short version is that Rize and Syaro end up holding hands, in what is effectively the climax to several chapters of Syaro stressing about being separated from Rize by their "divergent paths", and the two will be much closer together and more direct with each other afterward, with one of their last couple major chapters together effectively advancing their story from just Syaro having a crush on Rize, to effectively their first date.
It's subtle, but they get a lot of help from their friends, including Chiya and Yura, in getting there!
- The Cultural Festival story arc is gradually revealed to be mostly about Syaro and Rize - this is the chapter where they finally hold hands, with a little help from their friends.
- Note that Syaro is afraid of rabbits, and there is a double-meaning for the Wonderland "nightmare" story.
- Syaro's flashback is to V11Ch142.
- Yura plots to mess with Rize through Chiya!
- Chiya's remark to Cocoa about "recognizing the expression" is a reference to Syaro worrying about losing Rize.
- Maya makes a pointed remark about holding hands, which will become important shortly.
- Rize tells Syaro that their "roles aren't defined" yet (interesting!)
- We get an explanation for why Chiya likes spooky things.
- Fuyu's remark about the Ghost Hotel in the city, and Chiya's remark about Yura's role in suggesting "that last bit", reveal how involved they both are in the plot (and we might assume Maya is, too, based on her remark about holding hands!)
- Rize and Syaro reflect on ChiMaMe beyond the window, this is a callback to V05Ch12.
- Cocoa's mom is scared of running into Chino's dad? (I wonder what that is about?)
- Other supporting characters featured: Fleur's Manager and Class Rep Mai appear, along with Rei, Kano, Anzu and Nacchan; Anzu is a fortune-teller.

- V11Ch140-V11Ch142 (Ciste III, Beach) A theme of divergent paths coming back together. Rize and Syaro are getting along very well now, compared to the awkwardness from V11Ch131. Rize and Syaro playfully chase each other at the beach in Ch142.
- V12Ch147 (Hypnotherapy) We get another variation on the running gag about Rize, Chiya, and Syaro as parents and child; Syaro is "mama" this time. Syaro remarks on working with Chiya, a question that has been up in the air for many chapters by now.
- V12Ch151-V12Ch154 (Cultural Festival II) (as noted above)
- V13Ch165-V13Ch170 (Halloween II, World End Rabbits) Another cameo from Fleur's owner; Syaro took Rize's costume request from V06Ch06 ("...but I wanted to see you in other costumes as well, maybe as a devil, or something?"); bondage items Yura bought to tease Rize in V11Ch139 reappear in Rize's costume; Rize to Syaro: "want to cop a fluff?"; we get another interrogation scene with Rize; Rize and Syaro grope a disguised Yura; Cocoa recognizes Yura's perfume again; the arcade is a callback to V07Ch02.
And, from there, Rize and Syaro don't get much "screen" time together:
- V14Ch174 (Suspicous Persons Not Allowed) Syaro & Aoyama. Natsume and Maya remind Aoyama of a romantic comedy, and a romantic comedy reminds Syaro of Rize. Another cameo from Fleur's Manager. Syaro has grown up a lot by this chapter. A setup to "Ten Worldly Desires". (Since Vol. 11, the drama around Syaro leaving seems to shift to Chiya!)
- V14Ch177 (Christmas III, Continued) A Rin chapter. Callback to V03Ch10? Chiya has been worried over Syaro and Cocoa leaving.
- V14Ch181 (Crown and Bear) Carnival games with Chiya, Syaro, and Chino. Chiya mentions Syaro's and Chino's entrance exams. Fuyu wants to become the Bright Bunny poster girl. The crown is a callback to V07Ch01.
I didn't notice on first reading just how often Yura played "match-maker" between Rize and Syaro, while making it look like she was teasing them both.
The running gag about Syaro, Rize, and Chiya being a family, rotating the roles of mother, father, and child between them, are interesting, and on second and third reading, I couldn't help noticing how often these three characters are posed together, with Chiya in the middle. There's more than one panel where Chiya admires Rize's more revealing outfits!
Chiya frequently comments on scenes between Syaro and Rize with interest (she and Yura are the only characters who seem to notice the chemistry between them). Also, see V14Ch175 and Ch178 for some interesting scenes concerning Yura and Rize, such as Yura saying something about "switching roles" with Rize (seems likely to have been a double-entendre), and a flashback where it seems that a young Yura was too shy to approach Rize to learn how to use a blowgun; that flashback puts Yura's interactionns with Rize in an entirely different light, given that she was introduced to us as the president of the blowgun club back in/around V04Ch09, when Rize and Syaro support school clubs while investigating the identity of "Miss Emerald" together.
