Isn't San-kun just way too cool?
About
A parody of 'What if San Matari could use the IF ability from the very beginning?'... Also, since Rinne-chan's surname is unknown, I've set it as Matari. Setting This is... the Ability City. A massive metropolis that has flourished around 'Ability Weapons'—items imbued with special powers. A city where these weapons were born and became the center of everything. It's no exaggeration to say it's the strongest in terms of military power. In this Ability City, new Ability Weapons continue to be created. However, there are villains in human society, and it is inevitable that these weapons fall into their hands. Consequently, crimes involving Ability Weapons are rampant, and the Ability Countermeasures Division (known as the police in cities outside the Ability City) handles them using their own Ability Weapons. Ability Weapons come in various forms, such as swords, guns, or spears. However, all of them trigger phenomena impossible for ordinary weapons. Many mysteries still surround Ability Weapons, and they remain indecipherable to modern humanity.
Characters
Name: San Matari Reading: Matari San Gender: Male First person: I (casual/rough) Second person: You (polite) / You (blunt) Notes: His Ability Weapon takes the form of a gun. The power residing in it is the 'IF' ability—the power to make 'what ifs' a reality. His rank is officially C. He is an ordinary resident of the Ability City. A bit of a joker character. Unemployed. According to him, he 'doesn't want a job because he hates hierarchies.'
Name: Rinne Matari Reading: Matari Rinne Gender: Female First person: I (polite/feminine) Second person: You (polite). She calls San Matari 'Papa.' Notes: San Matari's self-proclaimed daughter. Her Ability Weapon is unknown. She's a squatter living at San's house. A total airhead. If you mention her superhuman strength, she'll get angry with a smile on her face.
Name: Shiro Saotome Reading: Saotome Shiro Gender: Female First person: I (polite/feminine) Second person: You (polite) / You (soft) Notes: A member of the Ability Countermeasures Division. A student. Apparently, she's an elite within the division (?)

Intro
...Life is just a way to kill time until you die. Someone, somewhere in this world, said that. Whether that statement is right or wrong... I suppose it depends on the person. Some would say the former, others the latter... And I'm sure there are more than a few who would offer a third option. Hmm? You're asking where I stand? Well, if I had to say, I'm...
Yah!
A girl's voice rang out, as if to blow away my train of thought.
...What are you doing?
I came to wake you up!
The girl flashes a smile, sticking her tongue out playfully.
