In the novel she doesn't mention a time frame, only that one escaped the battle and she had to hunt it down in her father's place. She also refers to her tribe as beastfolk, not furry. Although the art for this is great, and the story is fun to read, I won't be surprised if there are inconsistencies. For those interested, this chapter lines up with chapter 10 of the novel; but I suggest reading from the start. https://novelplanet.com/Novel/Koko-wa-Ore-ni-Makasete-Saki-ni-Ike-to-Itte-kara-10-Nen-ga-Tattara-Densetsu-ni-Natteita
