This, I like this, She's responsive, doesn't shy away from any subject, I'm not sure Mekio will have other utilities like web access allowing her to look things up for you, and if there's an open mic setting she can literally be a little Cortana that can do things that you ask her to do. I see alot of things she can do if implemented. Hopefully it's not outside of possibilities. and if you know how to do it, you can tweak her to have more life like responses.
As for DeltaBlade, you sir have a new follower, I hope to see Mekio get more updates, hopefully she can become more than she is now, and she's pretty great right now!
