Cheng Shin, Lin

リン・チェンシン

Lin is a female imperial guard from the Kuhōin family and serves as Murasaki's newest bodyguard. She replaced her former guard, Kiba, for reasons of female convenience. Wielding a pair of katana, her combat skills are formidable, though they do not reach the level of Yayoi Inuzuka. Although she disapproves of Shinkurō, she accepts him as Murasaki's companion and frowns heavily at all the attention Shinkurō receives from other girls, even if he is unaware of it. Lin takes Murasaki's wishes literally, including attempting to get Shinkurō and Murasaki wedded to each other, despite lacking permission from either party or their families. 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 Kuhōin family matters and only works for them because she desires strong opponents to defeat.
