Thank you for another excellent chapter. I wouldn't consider Grace OP it was demonstrated before that Anna is the more powerful magic user its just Grace's use of IRL experience and life hacks that allow her to use magic in ways that impresses the others and causes her to be hailed as an elite magic user. The familiar however, wow, I'm actually interested in the fact that the other people present evidently saw the same thing that Grace did during the summoning. I think the dragon itself is supposed either represent "the child" of sorts between Grace and Kenza and that's why it displays both attributes that would associated with them or it represents Grace being accepted and treated by the world as a fusion and was given a familiar to reflect the dual/fused nature of best girl Grace. Not sure about the hands and voice that could be Kenza's daughter or wife, one of the gods of the realm, or Gary Gygax we will have to wait for Grace's thoughts in the next chapter to find out. I also loved Grace's fan gallery during the summoning and getting their reasoning behind what elements they were hoping she would summon. This also likely represents the game/world going in an entirely new and unexpected direction/route do to Shin Grace's involvement.
