A female imperial guard of the Kuh�in family, Lin is the newest bodyguard of Murasaki, replacing her former guard, Kiba, due to female convenience. Armed with a pair of katana, her fighting skills are formidable, though not at the level of Yayoi Inuzuka. Although she disapproves of Shinkur�, nevertheless, she accepts him as Murasaki's companion, and frowns heavily on all the attention Shinkur� receives from other girls (even if he is unaware of it). Lin takes Murasaki's wishes literally, including attempting to get Shinkur� and Murasaki wedded to each other, despite not having permission from either party (or their families, for that matter). Under Murasaki's care, Lin is slowly learning about normal life, albeit with some difficulty. Lin is a completely different character in the anime TV series. She has no interest in the Kuh�in family matters and only works for them because she desires strong opponents to defeat.
