>>78105339She is effectively gone either way. Whether she gets a soft graduation like Bon the day her contract expires, or if she gets Zaion'd the day before, depends on the real reason for her months-long absence and Niji's willingness to ruin the post-Niji career prospects of the talent behind the Kotoka Torahime character (who lives in Japan and is subject to the entirety of the contract, and also to Japanese defamation laws).
>>78123180It would be nice if Sayu and Kotoka buried the hatchet, although management would very likely retaliate against Kotoka if they found out she offered an olive branch to Sayu, or accepted one from her. If talent reconciliation and management retaliation is the reason for Kotoka's "hiatus," then she absolutely will be terminated for it, even if for no other reason than to (try to) warn the other talents against giving Doki or Sayu so much as the time of day. When they'll formally do it will be either the day when they tire of selling cheap plastic merch with her face on it, or the day before her contract expires, whichever is earlier.
Remember that this same retaliation may be why Finana had to give her "Zaion gaslit me" speech, and is why Ren got a one week suspension for his "I don't hate Zaion Lanza" tweet.
