A: もう用がねぇなら帰るけど

B: 用がないわけじゃないけど 今日はなんかタイミングがよくない

A: じゃあ帰る **から** な

I would like to know if kara is used commonly in Japanese to say also "in that
case" (besides of "because"), or is it used as a softener or for another
reason in this context?

Thank you so much in advance!

question
grammar particle-から
Can から mean それでは?
In this case, as you mentioned, から is a softener, for making the parting of
ways not so harsh.

## Without the から: a bit cold

> じゃあ帰る
>
> Alright, I'm going home.

## With the から: adds the sense of "if there's anything else you want to talk
about, please bring it up now, because I plan to go home now."

> じゃあ帰るから（他に話すことがあるなら今話そうね。なければ、また会いましょう。）
>
> Alright, I'm going home, so...(if there's anything else you want to talk
> about, please bring it up now, because I plan to go home now.)

## EDIT (additional comment): Generally, the meaning of the "elliptical" から
can vary depending on situation.

A different example from the one above:

> もう、帰るから！
>
> I'm leaving! (...so don't talk to me, because I'm angry, frustrated, etc.)

According to 明鏡国語辞典:

> から 〘接続助詞〙  
>  ❻《文末に用いて》 **注意・警告・慰め** などの気持ちを表す。  
>  「先生に言いつけてやる **から** 。」「私もう帰る **から** 。」「心配しなくていい **から** 。」

The conjunctive particle から at the end of a sentence can express a feeling of
注意・警告・慰め (cautioning, warning, comforting/cheering up). Here in your context
the から is not "because" or "so", but expresses soft/mild 注意 or 警告, adding a
nuance of "~~, alright? / okay? / you see?" etc. It is daily used in real life
as in 「じゃ、(もう)帰る **から** (ね)。」「じゃ、(もう)行く **から** (ね)。」 etc. to mean "Well/Okay,
I'm going home / leaving now (, alright?)"
