A) This is foreshadowing - Ichi is not fully human and so him finding his identity amongst humans will be a key point later.

If Ichi is the child of a Majik and a witch (or even a Majik and a regular human - we haven't seen if Majiks can carry children, only that they can impregnate humans) then I'm betting they didn't leave him with a normal dagger.

B) There is a gem at the bottom of Ichi's dagger - I'm going to bet that dagger 'contains' a Majik.

(I have been corrected - it's Inazuri on the dagger. I forgot that was a thing)

Another thing:

Fujimine is not saying this because of the Mentor-Pupil pact Desscaras and Ichi made. It's tactical information, sure, but it's not something that would have made Haytee look like that.

One could say that Haytee is embarrassed about being intrigued by a human when they only have one mission. This could be embarrassment, but I feel Fujimine would tease a bit more. Here, she just looks like she found out some information that she can use, and Haytee knows this.

I've had a feeling for a while, since a little before the introduction of Majikeepers. What do you notice here?

Remember what I said earlier - none of these Majiks look human. The exceptions are at the bottom:

Hitsugi was pretending to be a human for espionage purposes. His actual form appears to be this sphinx/chimera-like thing:

And Chrono was purposefully taking on a human form to be close to Minnie and to conceive a child. Even in that human form, he had things that made him look inhuman, like feathers. Same with Bakugami, who has larger ears and oddly shaped hands and feet.

But we've never seen Haytee take anything other than a human form

And he looks like a perfectly normal human.

I've wondered for a while now if WHM isn't a Majik at all - perhaps he's a Majik-human hybrid, like Madoka and possibly like Ichi. This could be what Fujimine figured out.

I say I thought about this with the Majikeepers, because something struck me with his staff, Cynosura, - it's a lot like the Majikeeper's Sacred Treasures. I don't think they're the same - there would have to be a lot more reveals for me to make that claim - but I think it's curious. We don't see any other Majik holding a weapon like this.

It's also odd this lines up with the first appearance of the WHM 15 years ago, which appears to be Ichi's age, though he could be older or younger. A lot of people have suggested that this is part of the prophecy?
