Well something like Chronoire, Medusa(and her underlings), Weekend(sensei) is rather amusing to watch. Literally all of them have same purpose and that is to steal/get Evermillion/White Princess Power.
Chronoire actually have long (friendly?) relationship with Kazane, i had no idea what shes aiming but
shes the first one that open Takamiya seals.
Medusa (and shenanigans), literally the same as others antagonist, literally all of them aims White Princess Power but otherwise she is released by weekend? or was it chronoire? i forgot as a Chess Pawn. Despite that shes one of the "Legendary" witches. She easly defeat Kagari by just turning her into stone until Takamiya unlocked another seal and summoned white princess along it.
Shes the one who caused Kazane became homeless for sometimes and fell into debt (the fault not entirely on her since White princess destroyed her him just to deal with Medusaa)
Weekend probably the first main antagonist that works behind the scene, as she planned it all way back years ago and
she also show no mercy and hostility towards normal civilians (like bombing the tree root where those "Stars" gathered).
Yet despite all these rucukus these people cause they're still staying in city (along with their underlings and sidecharactes which also cause this random chaining events).
Chronoire literally living in city while observating Workshop which and making deals with Kazane.
Medusa that also gone for a while then return back living "Right in front of fucking Takamiya house " not sure why shes here assuming shes also waiting Kazane and Takamiya to make a move she also shows no hostility towards them.
Then theres Weekend who became a teacher assigned by Kazane herself after the torture.
I think this was foreshadowing something in future, as some previous chapter shown Alcina drawing the hierarchy of the City Witches based on Chronoire,Medusa and Kazane Circles. We're close to meet Kayou which is Kagari own blood related mother and it might occurs right after this Alcina arc.
Alcina arc might be staying in city like others,as she shown trust on Takamiya, following misunderstanding , past relationship with Evermillion/White Princess. It also hinted that White Princess used to be a normal witches(?) until she discover somekind of spell or wanting to became more powerful in exchange of her freedom.
I dont know how many plot relevant side characters author can give. Natsumi technically shown as an underlings back then,until recent chapter she always shows up 24/7, then Tanpopo literally became main character in the series(i lost count how many times she appears), Kasumi herself got an arc, and almost every character that introduced still appears in chapters is what makes me amused about this series.
