Nevermind, Snake isn't going to be fine..
We all know this Manga is tragedy and that there won't be a happy ending because the ending will be sebastian eating ciels soul but we still are here because we love to hurt ourselves ╥﹏╥. We will cry im pain because our favorite characters are dying and we will still read the new chapters because we want to see the ending, even though it won't be a happy ending. We all suffer together (▰˘◡˘▰) especially now, when snake is probably going to die ┗( T﹏T )┛
We are emotionally suffering!
Of course what happened to Agni was unnecessary and unpredictable because that's what murder is!! Agni dying made sense because he got stabbed tons of times! Agni is strong but he isn't immortal. Yana didn't do it just for the plot or just to be edgy. Plus, why do people think Snake and Finny are going to die? Both of them should be fine for now. If you can't handle tragedy then Kuroshitsuji isn't for you. Kuroshitsuji isn't a cute slice of life series lol you should know that by now.
