Nekozuka Hibiki

A member of the Engineering Dept. at Millennium School. Despite being unsociable and unsophisticated in speech, she exhibits a prominent natural talent in engineering and has invented many strange marvelous objects. Her inventions are practically flawless, and while it wouldn't be too much to call all of them masterpieces, there's always at least one bizarre feature included that leaves their users bewildered. Although she is rather introverted, she is quite dedicated with engineering and inventing, similar to the other Engineering Department members. Her passion leads to numerous unusual inventions. She also likes making cosplay outfits as her hobby, one being her cheerleader costume which was made during her first days of making cosplay outfits when she was younger. She enjoys cosplaying and helping others with her inventions. She also loves shopping, though can get a bit caught up in her shopping sprees. Her cheerleader outfit was actually made during her first cosplay days. Due to that, the outfit was smaller compared to Hibiki's current size. When she learned she had to wear the outfit now, she feels super embarrassed as cheerleading has never been her thing, not to mention having to do that while being viewed by many people. She works with Utaha and Kotori in making and engineering machines and robotics, and is probably the shyest of the group, never specifically putting herself out there, unlike the other two who do it quite easily. Hibiki also cares quite deeply about her Sensei, though she gets a bit shy when told to explain why that is the case. It's likely she has a major crush.
