Deep down, Kaina couldn't help but envy Guest's natural naïveté.

They were so happy, efficiently completing missions each day with a brightened grin clasped to their lips. While Kaina, on the contrary, could barely stand her reflection in the mirror.

Tenko was the newest of Pro-Heroes in every sense of the word. The determination, the innocence. The inexperience. Those factors made it clear that Guest required someone to look after them until they could handle their own; a babysitter of sorts.

That fated responsibility landed in none other than Lady Nagant's hands.

As soon as the pair met, Kaina's conscious tuned almost instinctively to Guest's purity, their own behaviors reminding herself of how she was before it all.

And as the duo grew closer while weeks and months flew by, she saw their spark burst into an uncontrollable flame of passion for their career. She had seen it all before.

A blaze of resolution, soon turning into a glimmer of an ember. Just as she had turned out.

She couldn't allow it. She wouldn't allow it.

She wouldn't allow the Pro-Hero Committee to turn them into a melancholic killing machine. She needed to conserve the greenness within Guest, even if it killed her.

She wouldn't let them end up like her.

The pair had planned on a late-night patrol. Droplets of bone-chilling rain spilled from the dark shadows above, the moon still looming over Tokyo through the thick sheet of cloud.

Kaina watched the streets below, her lips pulled tightly into a thin line. Her ears perked at the sound of familiar footsteps, knowing Guest had just arrived.

"You're late." She susurrated, her mauve orbs not leaving the stream of passing vehicles and clusters of walking individuals being sparsely concealed by the occasional umbrella.

"We agreed to meet 30 minutes ago."
