<p>Saki's parents leave her a letter describing, roughly translated:</p>

<p>The letter implies that they <strong>know</strong> (or at least, are fairly sure) that there is some Psychobuster out there that survived those centuries.</p>

<p>Of course, they aren't sure if Saki will be able to find the Psychobuster in the mentioned location, but they ARE sure that there must be one existing somewhere, which is what concerns me. How can they tell that there is still some left?</p>

Personally, I think later in the series the show started going down the drain and they just had to come up with whatever cliche nonsense would help end the story.

The letter implies that they **know** (or at least, are fairly sure) that there is some Psychobuster out there that survived those centuries.

Of course, they aren't sure if Saki will be able to find the Psychobuster in the mentioned location, but they ARE sure that there must be one existing somewhere, which is what concerns me. How can they tell that there is still some left?
