A girl with a taciturn personality who works as an information broker, following in her grandfather's footsteps. Her sources allow her to find information of all kinds, including new jobs for Shinkur� to help his livelihood. She has been Shinkur�'s friend since childhood. After he lost his family, she tried, without success, to cheer him up. When Shinkur� was about to be killed, Ginko tried desperately to save him. Because Shinkur�'s job as a mediator leaves him covered in wounds, Ginko constantly offers him a job at her family's ramen shop where she works part-time. She hopes that Shinkur� will quit his job as a mediator and come work (and live) with her. Ginko also likes Shinkur�, but isn't as open with her feelings as other female characters. Even so, Ginko notably gets irritated whenever other girls, especially Yūno, flock around Shinkur�.
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.
She first introduced herself as Sirzechs' maid. She was the one who relayed the Gremory family's request to have Rias participate in a Rating game against Raiser. She is in truth Sirzechs's Queen, both in the Evil Pieces and as the Maou's wife.
The Student Council Accountant (treasurer). She is also a ninja. Yuka appears to be carefree most of the time. However, she is very cunning, mostly encouraging activities of the Maken-ki that involve some kind of other work that needs to be done. The most obvious of these actions is the "match" between Venus and Maken-ki, where the players use broomsticks and soap while playing in the pool. She is close friends with Furan and likes to tease her. Yuka is also the younger sister of Takeru's homeroom teacher Tomiko Amado. (Source: Wikipedia)
President of Student Council
The main protagonist of the series. Despite his looks and easygoing personality, he is a capable and strong worker who works for Benika as a dispute mediator. When he was young, he lost his family in a terrorist attack. As a result, he became withdrawn from the world until he met Benika. He wished to be as strong as her so he could live on. Benika decided to leave him at the H�zuki household. It was there that he trained his body extensively and learned H�zuki-style martial arts. His kind demeanor attracts considerable attention from the opposite gender, though he is completely oblivious. In emergencies, he is able to produce a large 'horn' out of his right elbow which classes him as "Type 1 Class 2 Fighting Demon". This special weapon was designed for the purpose of assassination. This lets him use his full strength in combat, but shortens his lifespan. When he is forced to fight, his personality changes to a more aggressive one. Between the anime and the manga, there are differences in the way Shinkur� is depicted. In the anime, Shinkur� is not as confident and appears to have less control over the Hozuki horn.
