Aren't those things boars? Kikuru called them "lions", but those things are not lions no matter how you look at It. I'm guessing It was a bizarre mistranslation? lol
Also, the term "pride" can only be used when referring to a group of animals If the animals being referred to are lions, but I don't think that the author actually calls those things "lions", so the correct term for those, which I believe are boars, should be a "herd" or simply call It a "group".
Lastly, I'm not sure about this but, considering how the boars attack, shouldn't It's name be Ironhead, rather than "Irhaino"? I might be wrong though, but I think Ironhead makes more sense. lol
