[Kaneki shifts just slightly, moving his hand so Molly can have a better look at what he's written.]

Ah, well...it works a lot like any other system of symbols for a language, but Kanji can be read a lot of different ways, depending on what it is. There are a lot of different variants. It can be a little tricky to read, sometimes. But when you're writing Kanji, the parts of the symbol usually tell you something about what thing you're talking about.

For example, um...this is the kanji for water, and this is the kanji for tree.

[And he writes both...]

水 - water 木 - tree

[Like so.]

They look really similar, don't they?
