Haruka is a friend of the main protagonist Naoto Takayama and a member of the Fourth Vigilance Squad.


She is a girl with pinkish hair that flows down her back and very well endowed body. Just like all her friends, she wears her security uniform, which is made up of a top with a tie and a skirt, and a flesh-color pantyhose. She also wears black leather shoes.


She is a very shy and nervous girl, but she is good at studying. She is shown to have an outstanding memory, being able to memorize maps, which is also why she is so good at studying.

Background Edit

When she was very young, she was trapped in the basement of the Railway Museum until Naoto found her and rescued her. From then on she persued to become a JNR staff so she could meet Naoto.


Volume 1Edit



Naoto TakayamaEdit

When the two first meet, Haruka became embarrassed when Naoto looked at her panties. She is his first friend, which was when they were starting their railway classes. Even though there have been embarrassing moments, Haruka is always kind to Naoto. There have been some hints of romance between them. However, a love triangle of sorts seems to have formed between Haruka, Aoi, and Naoto, though none of them have admitted it.

Aoi SakuraiEdit

They met at the opening ceremony of the Rail Wars Academy. They soon became friends. She is the other female member besides Haruka Komi & Nana Iida of the Fourth Vigilance Squad. Haruka sees Aoi as both comrade and love rival.


  • Her school uniform somewhat looks identical to the school uniform of Misaki Municipal High School from the series Shakugan no Shana.
  • Contrary to her actual personality, Haruka is presumed to have yandere traits.
  • Apparently, she sleeps nude.
