I vote that the wolf be named Ralph.
Yes, that is a Rampage reference and I will stand by my vote.

update please

Hi great story hope you update it soon and for the name. Fenrir is a giant wolf destined to end the world by devouring Odin King of the gods and devouring the world. This wolf could be the heroic version of Fenrir by ending the age of Titans. Your story your choice.

For now is very good. Keep it up

This is really interesting. The plot with the wolf and his conection to Mikasa. Or vice versa. Also, your writing skills amaze me. Looking forward for next chapter!
