はぁ……と、のんびりした相槌

[zeroh4nter]

はぁ……と、のんびりした相槌。>> What does this mean ? (MC is talking with another character,after he made that person startled -because he approached this person while his hand is holding a sword )
G1: 剣抜いて何してたの？秘密特訓？
MC: う～ん、そんなようなものではあるかも

はぁ……と、のんびりした相槌。 >>Can anyone help me understand what does he meant with this ?

(my guess is " Hahhh..... She exhaled in relief ,show me an relaxed understanding expression" but i'm not sure)

You know what aizuchi is, yes?
My interpretation is that MC was responding/reacting to G1's comments in a very slow, almost lazy fashion. Whereas normal aizuchi would be things like: yes, right, understood, oh, is that so? etc...
But in this case MC is just responding by just saying, haaa... This indicates he/she isn't really engaged in the conversation.

For confirmation, the order of their words in the conversation is like this?

G1 said something like 驚かさないでよ
はぁ……と、のんびりした相槌。(はぁ was said by MC)
G1: 剣抜いて何してたの？秘密特訓？
MC: う～ん、そんなようなものではあるかも

So, it's like this?

G1: 剣抜いて何してたの？秘密特訓？
MC: う～ん、そんなようなものではあるかも
はぁ……と、のんびりした相槌。

Is it possible to provide us the whole sentences including after はぁ……と、のんびりした相槌。? The flow of the conversation sounds odd to me.
