Reid had things he was good at, and things he wasn't. Assassins don't tend to make great tanks. Reid died fighting a rather powerful demon while protecting a bunch of defenseless kids at the same time, which of course put him at a huge disadvantage in that fight. Not to mention they didn't go to a random orphanage all decked out in their fighting gear.
So Nicole is alone right now (doing her standard nightly training), but that's fine for the current situation. You're assuming a straight up fight from the front. No, no, no. There are bandits in a house at night who don't know they've been found. It is clearly "assassin time" - which falls cleanly within the "things Nicole is good at" column.
However thinking about the long term is not one of the things Nicole is good at. This event will soon lead to
Maxwell to figure out she's the reincarnation of Reid - along with a few other factors like the missing piano wire (from the school Maxwell runs) and all the various events in a short period from when Nicole arrived in town. Also one more major event that occurs after this - that will solidify Maxwell's hunch. But it is this event that first tells everyone "Reid's reincarnation was a success, and Reid is in Raum".
I find it funny that the adults didn't do more work than Reid aka the Heroes' daughter, even though she had proven enough times that her shenanigans led them to solve the cases smoothly. They're too relaxed after retirement.
Lmao I know this is probably an older novel but god, the running errands foe people you just met, the very convenient act of accidentally discovering the hideout, is freaking real.
