Bofuri: I Don't Want to Get Hurt, so I'll Max Out My Defense., Vol. 1 (manga)

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!
