そんなだから A little help for translation


I need some help to figure out how can I translate そんなだから.  
It must quite vague because it seems to lack a noun after そんな (such as
時、本、etc.). If it had such nouns I could understand it like "at this kind of
time, "this kind of book"). If I were to adapt it a little, would "It's for
this reason." I think literally would be "That's why".  
The action of this manga is that it's about saving someone from a villain. The
ones going against this villain is a group of friends, they are fighting with
all they got in order to save their captured friend.  
そんなだから-That's why/This is our reason (for fighting), (to save our friend).  
I hope you can understand...I don't know if I explained it so well.




According to [a
dictionary](https://dictionary.goo.ne.jp/jn/132095/meaning/m0u/%E3%81%9D%E3%82%93%E3%81%AA/),
そんな/こんな is a _na-adjective_ (形容動詞). It usually works attributively (i.e.,
directly modifies the following noun) and means "such" (そんな人 = "such a
person"). It sometimes works predicatively and means "(... is) like
this/that".

>   * 毎日こんなだ。  
>  Things are like this every day.
>   * へえ、もう彼はそんなですか。  
>  Oh, is he already like that?
>   * 君がそんなだと我々は勝てない。  
>  If you're like that, we won't be able to win.
>

This こんな/そんな refers to what's mentioned in the previous context or what's in
front of the speaker/listener.

Therefore, そんなだから naturally means "Because it's like that", "Because you're
like that", etc.
