Author an Idea for a future scene you could write; Let's say you make a confrontation between Accelerator and AFO, which seems INVETIBLE, we know that the evil mastermind is no moron, he will learn about Accelerator through his various feats that you may wrote sooner than later in up coming chapters from them and the description of his ability as the information (not completely accurate) is given by himself, he will realize Accelerator might have the one ability that may just be able to counter virtually anything he could through at him except anything that defy physics say telekinesis, he will of course test practically every quirk he has on him only to find out Accelerator might just practically be untouchable. So he come up with plan H after all other attempts at stopping him fail as he can't come into contact with him due to Accel's shield so in order to take what he perceives Accelerator's absurd "quirk" called vector manipulation, he is gonna need him to allow Accelerator himself to take it from him. Hence his plan H, the hostage. If by this point in story you write a character he is attached to in the same degree and magnitude of care as our canon Last Order the evil genius will absolutely take this person hostage. Basically force Accelerator to give up his quirk and defense for the sake of this person, Accelerator agrees with his own plan in mind as he already figured out that AFO's ability only steals quirks and no one in the world has any clue as to shag his Esper ability actually is! So he let's him do it pretending to agree while laughing on the inside it would be diabolical plot! From there on go and write there reaction!
