After reading NT 22R, this makes me wonder how are they going to react when they find out Accelerator is their boss now

Okay - Yomikawa has been trying to recruit her old friend into Anti-Skill.

Still, an enjoyable little bit of interaction between the characters.

Often enough when Yomikawa is off duty isn't it because of problems AT work (such as her unwillingness to back off when the higher-ups tells her not to investigate any further)?

And even with the events at the end of NT22, Accelerator won't be Yomikawa's boss. He'll be her boss'es boss'es boss (or something like that).

Now we're actually getting into the story (which makes half of that prologue redundant).

It seems more like you are writing a script or screenplay than a narrative. On the other hand, you're doing a good job expressing most things through dialog rather than description.

However, is there a reason why (Accelerator) is always enclosed in parenthesis, even when other characters are referring to him name?

Not sure what this adds. Were it not for the subsequent chapters having already been posted, after reading just this I might not have bothered to click on "Next"
