[Act 1] (1-2 scenes)
Introduction. Anon meets Chimata, who presents herself as the polite, yet somewhat arrogant goddess of markets, with an upcoming market that she's planning to hold at the upcoming flower viewing. During this act, the player is introduced to Chimata. She's likely to leave not the best first impression, which is fine since that's the point (if she left good first impressions, the perception of her within Gensokyo would be much different). The initial scenes should be fun and light-hearted that showcase arrogance and dorkiness. Sidnote with Chimata's arrogance, she should rarely if ever insult the player or others, she's still polite. Chimata's arrogance is more of building herself up as opposed to tearing others down. The former is endearing, the latter is bitchy. If we're going with the Marisa matchmaker angle, I imagine Marisa will comment that she hadn't considered Chimata as an eligible bachelorette for the player, but she's probably fine since "rich girls can cover all of your expenses".

[Act 2] (2-3 scenes)
Exploration of character. As Anon continues to meet Chimata, she'll begin to elaborate a bit more on her role as a goddess of markets, and what they mean to her. At this point, Chimata should make it clear to the player that she's not about the act of buying or selling, but special markets. At this point, the player should be introduced to Chimata's more personal world views, giving the player an idea that she's not just a dorky egotistical goddess. We should also see how Chimata goes about setting up markets, talking with vendors, diplomatically resolving potential issues, there needs to be a level of competence shown here on her part. Assuming the player picked the correct options, at the end Chimata will offer Anon the privilege to help her set up the market alongside her (Otherwise she'll politely explain that she has to focus on setting up the market, so she'll be too busy to meet Anon for a while). Choosing to do so locks the player into the Chimata route.

[Act 3] (2-3 scenes)
Rising tension. As the player begins to help Chimata set up her market for the upcoming flower viewing, they should begin to see the cracks in Chimata. Specifically, how she has struggled to set up or control markets on her own without the help of others, and that the people who do help view their relationship with her as purely transactional. The player should realize at this point that Chimata doesn't actually have anyone in Gensokyo that sees her as a friend, at best a business partner, something that Chimata insists doesn't bug her. One of her most shady ones being Megumu, the daitengu who is responsible for saving Chimata in the first place. On one hand, Chimata is uncomfortable dealing with her. Megumu is conniving, backstabbing, and doesn't have the same level of respect for the market that she does. On the other though, Megumu did save Chimata, and is trying to get back into her good graces again, likely to use Chimata for some scheme in the future. Chimata isn't ignorant, she knows Megumu wants to use her as a pawn, but she doesn't really know what she wants. Chimata's facade of an arrogant goddess should be cracking at this point, where it's clear she's struggling to live up to how she feels a goddess should be. If Megumu appears in person during this route, she should make dismissive comments about the player. This is very much our racist/sexist tengu society interpretation, though if the player is insane they might concur with Megumu's views, something which will pleasantly surprise the tengu. There should also be a scene with Keine, where she tells the player that Megumu and tengu in general are very bad news, and that you should never toy with a girl's heart. This is foreshadowing and should make it clear to the players what to avoid in a possible bad ending.

[Act 4] (1-2 scenes)
Emotional climax. Thanks to the help you've provided, the market for the flower viewing should be large and vibrant. Unfortunately, Megumu has decided to make her sway known, and demands Chimata do something shady, which will undermine the purpose of the market but benefit the tengu. Chimata tries to argue against it, but Megumu says firmly that she owes Chimata this. Without her, Chimata would be dead, and Megumu has stuck her neck out for the goddess plenty of times before. Chimata should lay out firmly all of her fears and wories to the player, about how she's frustrated and feels like she's drowning in a world that's long moved passed the need for her. For her, markets should be honest, fair, and fun. But the only people who seem to work with her just want to manipulate them to be sketchy for-profit ventures intended to screw people over, and that people think of her in the same manner. The player should reassure Chimata that she's been stronger than she thinks she is. Chimata will argue that she's not, that she only acts that way, at which point the player can point out to previous events in the route where Chimata showed strength or initiative. Chimata, feeling a newfound confidence and hope with her place in the world, will at this point realize how much she loves the player, and awkwardly try to thank him with sex, but finds herself too emotional and inexperienced to go through with it. The player reassures her, and instead they spend the night cuddling under the stars, with the player talking about them.

[Act 5] (1 scene/ending)
Eucatastrophe. The market at the flowerviwing goes off without a hitch, and is incredibly successful. Everyone is having a good time, as Chimata and you stay afar, watching over everything (though Chimata sends you off every now and then to be her ears on the ground, you learn over your time that despite being a goddess of markets she's a bit more introverted than you'd expect, specifically around large crowds). In a back area, Megumu confronts both of you in disguise for not doing her plan, to which Chimata confidently tells Megumu off. Chimata won't be indebted to the tengu forever, so she'll either have to participate in the market as an equal to everyone else, or take a hike lest she incurs the wrath of a goddess. Megumu will be surprised, but ultimately concede, telling Chimata she's grown a lot since they first met, though assuring both of you that there's still plenty of deals you'll make in the future with her. She flies off, and after Chimata comes down from that emotional outburst (even she's shocked that she stood up to Megumu so directly), the two of you decide to return to the marketplace, and do some shopping yourselves amongst the cherry blossoms. The sex scene, if there is one, can come that night at some luxorious inn within the village, while fireworks are going off.

(Potential Bad End)
If the player picks the obvious bad choices during the Chimata route, agreeing with Megumu's views that human boys exist for the pleasure of their betters, telling Chimata that she has the player as opposed to encouraging Chimata to build up her self-confidence, etc., Chimata will snap. She'll believe that she needs the player for emotional support, validation, everything, and it's her right to have him since she's a goddess. So she'll outright buy Anon, taking ownership of him. Being Chimata's pet/husband/boytoy isn't the worst fate, but you wonder if this was really the way it had to be. Megumu certainly doesn't complain though, as with Chimata using you as a pet and emotional outlet, she's free to manipulate and control the goddess as she pleases, securing the tengu's power within Gensokyo for generations.

(Joke Post-Credits Epilogue)
During Chimata's early route, she'll tell you about how she's heard, in the summer, that an overseas country decorates all of its stores and markets in rainbows. This act is surely meant to commemorate her, and that, if she built up enough faith in Gensokyo, she could take a short trip to the outside world and to this country and witness it for herself. After the success of this market, a few months later she takes the trip with Mamizou to see this overseas country and the praise they're no-doubt giving her!

She comes back a few days later and bitterly doesn't want to talk about it.
