Hiromitsu Morofushi: I have an older sister.
His police academy classmates: That's right, we have an older sister.
Hiromitsu Morofushi: When we were little, she used to sing me lullabies.
Some shogi player: That's right. Chiki's singing is so soothing.
Hiromitsu Morofushi: ...Later, my sister became an excellent prosecutor.
Some elementary school student: That's right! I knew Chiki was one of the good guys!
Hiromitsu Morofushi: ...
[Wait, Chiki, how many younger brothers do you have?!]
Morofushi Chiki, after getting a call from her adorable little brother: ...Hm?
*
Morofushi Chiki always thought both her younger brothers were good kids. Then she kept dreaming that her most easygoing younger brother had become an outlaw who killed, robbed, and committed every kind of crime, and even teamed up with his childhood friend to swindle little girls at the station. Her gaze suddenly turned sharp.
Young Hiromitsu, feeling his sister's death glare: ?
At a loss, the child instinctively tried to seek help from his older brother. He turned around and met the equally stern gaze of Morofushi Takaaki.
Hiromitsu Morofushi: ???
Is this what you twins use your telepathic connection for?
Chiki began watching her brothers' upbringing and mental health from a young age, and saw her youngest brother, Hiromitsu, all the way through police academy. By then, her twin brother Takaaki had become an excellent detective, and she herself had already passed the prosecutor's exam. Just when she thought the Morofushi family had a bright future, Chiki had another prophetic dream: her youngest brother still became a member of a criminal organization, even earning a codename based on a type of alcohol for his excellent work. But later, he died at the hands of another member.
Morofushi Chiki: ...
Morofushi Chiki: Seriously, you're still bent on doing this, you little punk!
Morofushi Takaaki, clearly caught in the crossfire, tried to calm his twin sister down as she was about to explode, while signaling to his younger brother to get out of sight.
Then he had the same prophetic dream, too.
Morofushi Takaaki: ...
Morofushi Chiki: Hmph.
Hiromitsu Morofushi: An awkward smile.jpg
The eldest sister and brother of the Morofushi family exchanged a glance and joined forces from then on, determined to save their little brother.
Chiki's guide:
* She's Takaaki's twin. Since they've argued about who was older since childhood, they eventually decided to each use their preferred title for the other.
* Her childhood experiences made her fiercely protective of her younger brothers.
* Her main goal is to keep her youngest brother from dying, and while she's at it, save the other younger characters, too.
* A staunch, utterly devoted member of the good-guy faction (100% on the good side).
* Family-focused, no CP.
* There may be brief cameos from sports anime characters.
Theme: Family means having the courage to overcome every obstacle and run toward one another.
