Sword Art Online Alternative Gun Gale Online, Vol. 7 (light novel‪)‬

A BRAND-NEW BATTLEFIELD AWAITS!
During any difficult encounter, whether in a game or in real life, it's always good to have an exit strategy. In Karen Kohiruimaki's experience, when she gets questions like "What's your type?" she's able to respond with a smooth "Someone like P-Chan..." But when a handsome man appears during Llenn's Fourth Squad Jam strategy meeting and surprises her with a marriage proposal, she gets a sinking feeling that this is one battle she'll have to face head-on!
