防空埋護姫
Second boss of map E-4 in the Fall 2017 Event in [[Kantai Collection]].

Most likely an [[abyssal ship|abyssal]] version of [[Suzutsuki (kancolle)|]]; the "buried" part of her name, plus the [[chain]]s and [[anchor]]s keeping her immobilized probably refer to Suzutsuki's eventual fate as a breakwater.
