Of course, it all goes wrong. That's his life. It has to go wrong.
She's all jittery again, forgets to answer his questions. They're shopping for new pencil cases and he wants to show her what the human stars look like, because apparently she comes from another world and the constellations are different there, so they need to get a telescope. She almost drops the bag a couple of times and only the idea of burdening him with the heavy items makes her not hand them over. He's not that scrawny, really. For some reason, he thinks her hands should be free.
There's someone following them, he realizes when they stop for lunch. The realization is slow and he curses his lack of awareness. He likes science. Scientists observe, they're aware and yet someone is following them, two little kids.
And it makes his Nat-chan jittery.
(His, he thinks back, his, why is he possessing her like this?)
She takes him down side paths and ignores the protests because adults don't stalk children without a very wrong reason. He doesn't like this; it makes him sick.
He looks at her eyes and they are amber-cold.
"I'll protect you," she says, and though the eyes are cold, they are also resigned and scared.
Akihiro hates whoever it is that is making her wear that face.
Unfortunately, he still believes her.
