Kujirai did not have any particular intentions of pulling off the perfect crime. Never an avid reader of detective novels- in the first place- he didn't have an accurate understanding of what the term perfect crime even meant. At the point his hands were sullied in crime, he understood all too well it was leagues away from perfect; to start with, if such perfection truly did exist, Kujirai would never have had to retire from the world of competitive swimming—his unrewarded present state had already been proven by the world as a whole to an unnatural degree.
However, even if it wasn't perfect, the need to aim for perfection was only human nature, and even if it was impossible to achieve completion with the whole, perfecting an individual part of it was a conceivable possibility—or so Kujirai thought. Otherwise, there was far too little salvation. And as long as one portion was complete, it was surely possible to feign completion in the larger picture.
Taken to the logical extreme, no matter how much evidence remained, no matter how clear the motive was—as long as the suspect's alibi was unshakable, then as far as the law was concerned, it was impossible to make him out as guilty.
Alibi—right, the proof of absence from the scene.
The evidence he was not at the site of the murder.
Originally, that alone would be the minimum necessity.
And so it was, that on that day, at three in the afternoon, Kujirai found himself walking around the business district to forge his unshakable alibi; it wasn't as if he had any concrete plan. In order to aim for perfection, to move however the situation called for, Kujirai intentionally neglected to plan out the details. If he scheduled out the finer details, the evidence might remain, he convinced himself somewhat neurotically. From the start, Kujirai knew he would definitely be placed under suspicious once the matter came to light—he may have been paranoid, but it was a justified paranoia.
Now then, the most reliable evidence would have to be being witnessed by a large number of people, and have them testify 'he was there', however society is blind to the individual to a surprising degree. When it wasn't famous by any accounts, if he wanted to leave an impression on a great many 'eyes', he would either have to cause an outburst in public, or take some eccentric behavior, but if possible, he wanted to avoid standing out or the worse. Gathering strange attention carried a danger of hindering his actions thereafter.
That's why, at most, as natural as could be, he needed to leave an impression on a third party—third party. Right, it went without saying that whoever testified to Kujirai's alibi would have to be a third party—and the more of a third party they were, the more complete his alibi would be.
He had heard that family testimony was too weak for an alibi, and in that case, a close friend's words couldn't be too strong either—the most desirable person was one with absolutely no relations to himself, if possible, someone he was meeting for the first time.
With that on his mind, Kujirai prowled the main street—he came to a stop. More precisely, his eyes came to a stop—his eyes locked onto a single woman reading through a paperback as she elegantly sipped her coffee on a café terrace.
It was a sight that made for an exceptionally pretty picture. As her hair was all white, for a moment, he misread her age, but on closer inspection, she was a young woman whose age wasn't much different from his own. It would be quite odd if she was dying her hair to be fashionable… but her tight skirt that went to knee length, and her three-quarter-sleeve blouse gave off a charmingly down-to-earth aura. The glasses she wore made her seem somewhat intellectual.
Of course, to Kujirai, there was absolutely no need for her to be the one giving testimony—anyone would do. It could be someone from the next table, or just as well the table across. But how miserable would it be if he spent too much time being nitpicky and he exceeded the three o' clock he needed an alibi for?
With that on his mind, the white hair began to look convenient. With that characteristic hairstyle, she should be considerably easy to search out at a later date—especially with beauty on her level. Surely she will be the one to prove my innocence—Kujirai thought as he approached with a grin.
