In the light of the last chapter. Whoever likes post-timeskip!Shinji's hair, raise your hand! :))
The first time Shinji asked her if he should change his hairstyle, she had replied, "Sure, go ahead. It's not like it can get any worse than that."
He had yelled at her, she had flung her sandal at him, they had argued some more and all had been well. And Shinji had indeed followed through his suggestion.
Except that, when Hiyori had answered, she hadn't expected him to take her words as a challenge.
He was beaming at her, with his brand new hairstyle, which was essentially the same. Still the same pageboy cut, but this time he had showed oh so great originality (note sarcasm) - his bangs were asymmetrical (maybe, it was some kind of a metaphor connected to his zanpakuto; hell if she knew that stupid blonde's thoughts), the left side of which was longer than the right, falling in his eyes again.
It made him look more like a monkey than he already did.
Which is saying a lot.
At the sight of that monstrosity she cringed and hit him over the head when he asked if it suited him.
"Like it does, you baldie! Hope that hair gets in your eye!"
A few thousand years more and maybe he'd get rid of those stupid bangs and not let his eyes be covered by stupid wispy strands.
