Pre-Oracle:
🏹 After Liem showed up at her home to reveal that he had somehow received her original eye from Cetina via the Timestream... Hayame took him as a guarantor and contacted a certain vampire hunter named D to induct him into the Anti-Demon League and ask for his help searching for a skilled surgeon
🏹 When Cyrus put out the notice to shard-bearers about sensing an incoming Oracle, Hayame spoke with him about Meridian actions going forward, made plans with Itachi, Yuri, and Gray to hunt down potential Zenith cornerstones in Springstar, asked Nebula not to badmouth Cyrus in public for the sake of presenting a more united Springstar front, proposed all Zenites be "escorted" pre-Oracle to prevent spying, and reported her strange dream in Set's information gathering circle
🏹 At the traditional pre-Oracle gossip info sharing post, Hayame provided information about her own skills while also threatening to kill traitors to the cause and offering guidance to new Meridians (wow gee wonder why no one is taking her up on that...), she listened to Set's Big Gun Plan, vouched for the god and his information skills, vouched for Yuri's healing skills, discussed plans with Akua, gave advice on how to handle Dark, told Drizzt to choose a gd side, and um...
🏹 Most unfortunately, she (CW) told Rudbeckia to dissipate herself if she was going to be a useless neutral party who would help Zenith during the Oracle trial, and she... finally unblocked Voryn to defend Claude but it devolved into their usual fighting... and then somehow Voryn narrating sex with Sebastian Michaelis like a letter to gd Penthouse before she called him a whore traitor and reblocked him
🏹 Hayame then went on a Cornerstone hunt through Springstar with Yuri, Gray, Itachi, and Byleth, trying to prevent Zenith from getting the jump on them from within their own city once the Oracle manifested
🏹 She also honored her discussion with Cyrus and hosted a few displaced Springstar families (maybe quadruped ones) on her Alenroux property for the duration of the evacuation period

During the Harbinger Oracle: (mostly already reported in event actions)
🏹 Once the Oracle did appear, she monitored cornerstones for a bit then raced for the effigy in the garden maze
🏹 After waking in the Iconoclast foyer she left with Akua, intending to work with her for a while, but oops teleportation
🏹 She ended up in a magical/physical puzzle trap with Dimitri, and they eventually disarmed it but she lost her eyepatch in the process
🏹 Though she was not pleased to encounter Rin, a Zenite she is on decent terms with... this is an Oracle, so she shot her in the shoulder before the other woman managed an escape
🏹 Next she encountered Childe and got into an immediate mutual injury archery shoot off with him until the maze separated them
🏹 She then ended up with a word-based trap with Yuri, who had to help her solve it because she was stumped, which eventually outed her illiteracy to him and inspired potential lessons in the future
🏹 After going through the Long Hallway and choosing the familiar door, she was stricken with heartache and briefly collapsed into Shez
🏹 An Indiana Jones-style boulder trap meant Hayame had to swallow her pride and let Claude ride her so they could barely outrun it and jump over a huge pit... which ended up giving her a romance realization/breakthrough while kissing him on the floor oops
🏹 In the Hunger Room she was temporarily waylaid into conflicted makeouts with Akua but focus won out and they eventually managed to leave
🏹 Though she was destroying supplies whenever she found them, she did share hers with Meridians in need, such as Byleth
🏹 A temporary distraction in the form of void!orphan students could have turned deadly but for Nebula's interference, which allowed her to survive and they defeated the shadows
🏹 Predictably, running into Voryn almost resulted in violence until Silco suddenly showed up... and they teamed up to dissipate him, though his shard bounced away into a hole (onto Quetz eventually), robbing them of the chance to shatter him grrr
🏹 When trapped in the Offering Room with Set, Hayame cut off her beautiful mane for the effigy, a symbol of the femininity she has finally just begun to accept, the method through which she worships the god of war via combing her violences from her hair to his, and a poignant part of the intimacies she shares with her (no longer?) secret lover
🏹 Finally, void!possessed Fane attempted to kill her, but she fought back to eventually neutralize him... and though she hesitated to touch his shard to the effigy, not knowing if what he did accomplish before being possessed would count positively or the end result would count negatively, she eventually touched his shard to the effigy after hers
🏹 She then emerged from the Oracle labyrinth to find that Meridian had won... but um... why are her neighbors in Alenroux looking at her like that?????? P- People are actually being nice to her? She's being praised? What's happening?
