How many siblings does Tonnura have? From chapter 7 we know that Tonnura and Duke are brothers:



The next chapter, though, implies that Duke may not be Tonnura's only sibling.



Has it been revealed how many other siblings Tonnura has? And do we know anything about them (in particular, are they all large talking cats like Tonnura)?
Tonnura is one of 7 siblings, but only 4 have been revealed as of volume 7 of the manga. They are:

Tonnura, the titular character (and elderest brother)



Duke, the younger brother



Charmy, the youngest sister



Donsuke, the youngest brother
