Rune Factory Frontier Questions Options

[Jason]

Got an email from the site mail, if someone could kindly answer these for me:

Hi there. Right now, I'm playing Rune Factory Frontier and I have a few questions:

1. Where and when will Iris Noire appear? How do I get her to appear?
2. In the clock tower, if Kanno's in his room, I can't get in because on the door, it says, "Swing your fist and the door shall open." What does that mean? What do I have to do?
3. What's the max level of Raguna?
4. I bought a book from Selphy the other day, but I can't read it. I tried going to my inventory and stuff and I did find the book in the 'recipe' section, but I can't read it. How come?

That's all for now, I do hope that you write back as soon as possible.

Thank you for your attention,

Clow.

Thanks!
