Oh I didn't recognize that I read the novel before because I'm way too used to the novel art, so I didn't recognize it through the manga art, and it's been ages since I last read the novel. I really enjoyed reading the novel, it was really cute, and can't I wait for more manga chapters ε=ε=(ノ≧∇≦)ノ

Just make an account, its free, and you’ll be able to read it+bookmark your chapters and get updated when new ones come out

Also tip for finding novels try searching the mangas name+novel and it should pop up. So for this one you’d look up “im going to raise a hero novel” and then maybe add bl or yaoi to it. So “im going to raise a hero yaoi novel” and if theres a novel updates link try that one first if not any other. Sometimes if you look up mtl you’ll get the machine translated one and those typically have all the chapters. Another website to try is mtlnovel.

Like the others said, I think she is actually a phoenix and not a "cursed eagle". I'd be surprised if she doesn't turn out to be a pheonix because there seems to be a lot of clues suggesting she is one with how her hair turned from blonde to a bright red, she has extremely powerful healing abilities, when she died she regressed back to when she was younger which is kinda similar to how a pheonix comes back to life as a young bird after death, and the eagle clan's healing abilities were said to originate from an ancient clan (which my theory is most likely the ancient clan is a phoenix clan or something like that). Also pheonixes from mythologies are said to grow stronger/more powerful after death so it also makes sense why her current powers is stronger compared to before she died.
Halfway through chapter 2 I thought it was cute, the two of them were slowly warming up to each other (despite mc not knowing the wolf was the ml). But as soon as I read the end of chapter 2 I just facepalmed so hard.... Directly telling him he's heartless just because he killed others? And because of what? An assumption? How does she know it was a human he killed and not some beasts that intruded the area? Even if he killed a human, she didn't even hear the reasoning because for all she knows, it could be an assassin aiming to take his life.
Also, even if he was truly a horrible and heartless person, she is literally a nobody from another country. If she was truly convinced he was such a horrible person then why would you say it to his face? He's literally the emperor and its been what, 4 days since they met each other? She's asking to be killed and tortured...
