Hi there! I don't think anyone did a translation for Chapter 11, so I went ahead and did a rough one in case anyone wants it.
Please correct me if you see any mistakes or you have a better interpretation of the dialogue!

Cover page: The wings that are spread out predict fortune…or misfortune…?!
Vertical words on the right: Hosokawa Gracia’s sudden attack! Chikahito, who just transferred school to Kyoto, is faced with a potentially fatal danger!?
Masamune: Speaking of which, in the [past], you didn’t have an oni.
Gracia: I had never entered the battlefield before, obviously.
Masamune: Often, onis who made a contract with females have powers of foresight and clairvoyance, or are able to control a person’s heart. I wonder your oni is which type?
Masamune: My heart won’t be so easily controlled by you! Because it belongs to Hana! (sfx on top: HAHAHAHAHAHA)
Gracia (to her oni): Shut that idiot up.
(The words below Hana: Masamune’s dream)
Gracia’s oni: Yes, mistress.
(The word on Gracia’s oni: takes off clothes)
-nothing to translate~-
Chikahito: Watch out!
Masamune: This oni is so fun, Tama.
Gracia: It’s Gracia.
Masamune: Alright then, I’ll play with you for a bit with my adorable oni.

Masamune: And also, this is Kurikara
(word on the last panel: hides)
Masamune: (T/N: I’ve no idea what 小鹿 in here is supposed to mean. Direct translation means ‘little deer’, but I’m not sure. Basically, Masamune is telling Chikahito not to be afraid (?), I think, and calling him ‘four eyes’ XD)
Chikahito: I-I’m not! And how is it possible!
(words on top of second last panel: hugs tightly)
Masamune: Hey hey, using this clumsy oni to play with me-
Gracia: That idiot, in the past, he talks big, and is annoying to boot.
Masamune: Only talking?! I can act on it too!

Masamune: GARYUU HOUSUU!!
Chikahito (to Kojuro): You can’t fight if you don’t shout our your name? (T/N: I’m sorry, I’m pretty sure this a wrong translation T.T)
Kojuro: Nope. It’s okay to be silent, but right now I have 小五病. (T/N: it’s the brick joke carried over from the previous chapter, when Kojuro said Masamune had this ‘illness’. EDIT: Thanks to sjou for finding out what it means! Direct translation is 'fifth grade illness' but it refers to idiots on the Internet.)
Top 2 panels: (T/N: I kinda understood the big picture, but I don’t understand the details, so I’ll just explain the joke. Basically, Chikahito noticed that Confucious had explained or spoken of Masamune’s sword’s name before, and so it ends up that Masamune is calling himself…something which I don’t really understand.
Masamune in the 2nd panel: YOU, FOUR EYES! SO NOISY! AS LONG AS THOSE WORDS LOOK COOL, WHO CARES!)
Kojuro: Masamune-sama, still so belligerent even when others stepped on your foot.
Masamune: ALL GUYS ARE LIKE THAT, OKAY!!
Gracia: I can’t stand this anymore. This must be what a true idiot is like.
Page 15 (T/N: EDIT: Thanks to aida_furion for finding Gracia's oni's name!)
Gracia: Nigemizu, hurry and get rid of them.
Nigemizu: Yes, mistress.
Chikahito: DATE MASAMUNE!!
Tachibana: She fell asleep here again.
Tachibana: Where’s that blanket.
The words on the left: The two Hanas meet in a dream…!?
T/N: Please correct me if you see any mistakes! This is my first time translating stuff and I would love to know how I can improve :)
