The Ramparts of Ice returns for a second season. The story centers on Koyuki Higawa, an awkward loner who keeps other people at a distance and has spent her high school days by herself. That changed when she met Minato Amamiya, a boy with no sense of boundaries who kept trying to get closer to her. Alongside the popular Miki and Youta, a kindhearted basketball player, the four confused teens share tangled lives in a mix of comedy, drama, romance and everyday school life.
