Spoiler for Vol3-4 stuff about Chiyu:

New character, Dusk Taker, shows up and uses 'Incarnate System' abilities (basically, non-programmed abilities that's (virtual) reality warping, for example Aqua Current's memory erasing) to steal Silver Crow's wings. Times it just right when KYH left school on a field trip, so the Black King can't put a end to this herself. DT plans to amass enough power to dethrone KYH, real-life PK her of all her points when she gets back.

DT then hacks Haru's Neural Link into setting him up for a crime, and then blackmails Haru into giving DT a offering of points every week or else be kicked out of school. Plans on using Haru as leverage to control Chiyu, as her Duel Avatar is a rare type that can heal people. Heavily implied DT wants to raep Chiyu and 'make her his bitch', so to speak.

Haru fights DT, on the verge of beating DT at the cost of never be able to fly again, then Chiyu steps in and heals DT. Haru and Taku was shocked at Chiyu's betrayal, then they both get their backsides handed to them by DT armed with IS abilities. Only IS abilities can counter other IS abilities, so Haru and Taku got owned hard.

Haru and Taku confronts Chiyu IRL after the battle, asking if DT is blackmailing her as well. She said no, she's doing this of her own free will, as she doesn't want to be weak. She made it very clear she is no longer friends with Haru and Taku, treating DT as much of a ally/friend with her words as she had treated her two friends. She was willing to let DT to keep blackmailing Haru, and doesn't plan on stopping DT.

Haru and Taku went training elsewhere to obtain IS abilities and fight DT. Chiyu and DT went kicking a$$ and taking names in Accel World, healing plus a winged person that rains down death from above (DT has long range armament items). 100% win rate in paired battles. Within days Chiyu raised to Level 4-5, the same level as Haru and Taku.

Haru blames himself for being weak, that Chiyu was caught by DT because of him. He told her he can't stand her being used by another man; he lost his wings already, he doesn't want to lose Chiyu as well. Chiyu cried and told him he doesn't understand her at all - even if her avatar is being used by DT, the real her no matter what is Haru's. She has not be taken by anyone.
She again states she is doing this of her own will - back then, and from now on too.

After training, Haru and DT arranges for a final battle, winner takes all. Evening of battle Chiyu told Haru + Taku DT had planned on her tricking Haru and Taku into going back to their side, and after entering help DT. Chiyu says she'll really be on their side, and either they take her along or she goes into the Unlimited Burst world before them or she'll wait for them until they arrive, no matter how many years it might take. Haru and Taku agrees to take her along.

Final Battle, Chiyu revealed why she joined DT's side: levelling up as fast as possible, upgrade her special gauge ability. She's not a healer/'White Mage' character - she's a 'Time Mage'. She turned back time of their avatar enough that DT never took away SC's wings. Joined DT for the sole purpose of stabbing him in the back.
After SC getting his wings back DT had no 'allies' willing to help him and was defeated by Haru. Chiyu joined the Black Legion after that.

OK... rage worthy and wow is she stupid... But ok. I get it now, thanks.
