Cutie Mori

That's Mori's mommy...

Ehhh? How u know? Plss spoil me ╥﹏╥

That thing is his mom?? How

Lol... sorry, it's not spoiler.
It's my deduction from what that thing said at earlier chapter (chapter 10 is it's 2nd appearance in this manga).
Plus it's movement kinda like it's care about Mori?

When this thing slowly move it's hand towards Mori, it was a gesture of "please come here, round one" (not like others with hand gesture like wanna force grab Mori).

This thing original purpose was to find Mori who has dissapeared from orphanage.
But because of the cloak Mori always wore, no one was able to find him.

Now, the first person who would know that Mori (specifically) is out there would be the people at the orphanage.
If a special child like that dissapeared, they would have reported to his guardian/sponsor.
And the guardian/sponsor would have been the only one who knows that Mori have a "cloak that can make him undetectable".

Plus this thing seems to have long black hair and exude elegance somehow. Lol.
