Lily Hoshina is one of the main characters in B: The Beginning. She comes from a family of violin repairers and is a detective that works for the Royal Investigative Services.


Lily is very immature, rash, and unprofessional, often behaving like a scatterbrained child.[1] Despite this, she is an extremely competent detective who takes her job seriously when necessary.

Lily loves food and won't miss an opportunity to eat and can be very driven when push comes to shove. Her intelligence and latent talent is on par with Keith's. Lily also enjoys techno music.[2]


Lily has straight shoulder-length black hair and brown eyes. She is left-handed, and comes from an Asian background [3].

On the job, Lily wears the standard RIS uniform, however, she wears more casual clothes on her days off.



Koku/Killer B

Lily and Koku are friends who know each other well because Koku works in her father's violin repair shop. Lily actually treats Koku more like a little brother and even offers to set him up with one of her girl friends.

At first, Lily is completely unaware of Koku's secret identity as Killer B and remains ignorant about until Episode 9, when she sees him transform for the first time. After Keith explains about Koku, Lily helps the pair out. After the case is over, their relationship goes back to normal with Lily now doting on Yuna as well.

Keith Kazama Flick

For most of the series, Lily is kept at a distance by Keith because of her resemblance to his younger sister, Erika and to himself.

At first, Lily thought that he was a weirdo, but eventually comes to understand that he is similar to herself. She hates being compared to Erika and finds Keith's fear about putting her in danger and his annoyance insulting. As they continued working together, Keith develops an appreciation of her skills, even though he still finds her pushy and annoying. After his sister's case is over, Lily and Keith become partners though they still get on each other's nerves.

Boris Meyer

Boris is Lily's superior at the RIS. He treats her like a daughter and constantly worries about her safety, while Lily similarly treats him like a father figure. However, Boris can't stand Lily's dangerous driving skills.
