Possibly could have been a witch...
Upon people not noticing us, if you look for it, there are a number of situations that are... suspicious in hindsight. Each explainable, but in sheer number for only the past couple of days...
In our first attempt, Kishi did notice us. We also jumped in and drew attention to ourselves immediately prior.
The second time, again Kishi noticed us when we drew attention to ourselves.
Possibly just sleepy, but again until Tamiko drew attention did not notice.
Asleep, and as we did not wake him up (draw attention) no attention drawn.
He does give an excuse in having to call his boss, but even while reading one of Tamiko's text books, he forgets to call her to say he was here. Believable.
Again, Tamiko surprises someone with her appearance. Possibly just because it is Kishi, but at some point too many coincidences become suspicious.
The witch did like black and white, but still strange.
Again, possibly the knights did not care because you wore black and white...
Something that actually notices Tamiko...
I just want to point out that the uncle was informed...
Ghost girl.
Going over the quest, Tamiko often escapes attention. As in, besides when people expect Tamiko or had someone else draw attention to her, (Catharine and the Doctor, Uncle waiting for her to come home) or someone (witch), or something does not happen to draw attention to Tamiko's existence (ordering food, text message or phone call) and perhaps once when Kishi telepathed us when she saw the ghost, but again we started the conversation...
Basically, if it isn't a situation where someone is looking for someone, Tamiko tends to not be noticed. It may be nothing, but we actually haven't been interacting with people in great numbers before this. And remember we are a ragamuffin currently, we should be drawing the eye at school.
And with this trend, Kimiko is our twin sister. If our Uncle called her, thinking about that call, or something she said after our wish may be enough to remind him of us if there is a wish going on. But frankly, I am very suspicious of this development, because we have witch familiars ignoring us.
