Animals Around Mt. Fuji

The Animals Around Mt. Fuji were seen in the titular area when Yu and Mika were traversing memories of the past. The creatures seen in the world of Seraph of the End are virtually the same as those in the real world around this geographical location. It is a rare occasion where animals were hunted for food given Yu and Mika's new plan in the making.

Birds
A number of small birds were seen within the forest which appeared undisturbed by human activity. They had also endured the Catastrophe event to begin with. Some birds are in the area such as on the abandoned cabin that Yu and Mika took up residence in.

Brown bear
In Japan there are two species of bear native to the country, the Japanese black bear and Ussuri brown bear. From the lack of the distinctive white section across the chest that Asian black bears have, and its much larger size, the bear that attacked Yu was a brown bear. This one had five very large claws. For the black and white panels of the manga, the species would indicate the bear's brown color it would have.

Boars
The Japanese boar is a sub-species with yellow-brown like colored fur. Two had been acquired by Mika.

Story
When Yu and Mika have concluded accessing memories having learned that Mikaela seemingly arranged his own plan with the homunculus named Yu, there was the need to acquire a food supply to save the rations they had previously gained. Evidently aware of animals in the Sea of Trees that is located around Mt. Fuji, they took to hunting the larger ones.

A feral appearing bear lunging at Yu was swiftly cut down by him in one strike. The first indication that it was to be eaten, two boars where then brought by Mika to Yu as well. They were roasted over a fire, cooked and eaten as Yu and Mika discussed a plan to resurrect Mikaela for a different means of resurrection.
