Christmas Rose is a side character usually seen getting defeated.

The story centers on Kaede Honjou, who is invited by her friend Risa Shiramine to play a virtual reality MMO game with her. While Kaede doesn't dislike games, what she really, truly dislikes is being in pain. She creates a character named Maple, and decides to put all her points in VIT to minimize pain. As a result, she moves slowly, can't use magic, and even a rabbit can get the best of her. However, as it turns out, she acquires a skill known as "Absolute Defense" as a result of her pumping points into VIT, as well as a "Counter Skill" that works against special moves. Now, with her ability to nullify all damage, she goes on adventures.<br><br>(Source: Anime News Network, edited)

Kaede Honjou has never been much of a gamer. So when her best friend, Risa, ropes her into trying out the hit new VRMMO NewWorld Online, her biggest concern is…whether it will hurt! Her solution? To dump all her stat points into defense! She may not have anything in the way of magic, agility, or strength, but her extreme build transforms her from a total noob into a nigh-invulnerable walking fortress the game’s admins never accounted for!
