Gathering spot during a shrine visit with 集合場所

Kanji Explanation: Joining and fitting with 合

Chiyo and her friends from class to go a new year shrine visit together. Chiyo remarks on how crowded it is.

歩(あゆむ):: 「あかんみんなはなればなれになってまうー」; “Oh no, everyone's going to end up separated!”
とも:: 「よし！集合(しゅうごう)場所(ばしょ)を決(き)めとこう！」; “All right! Let's decide on a meeting spot!”

Key Points

1集合(しゅうごう)場所(ばしょ) means “meeting place”

2決(き)めとこう is casual 決(き)めておこう

The spoken contraction compresses てお to と: 決(き)めておこう → 決(き)めとこう.
〜ておく treats choosing the spot as preparation, while volitional おこう turns it into the group proposal “let’s decide”.

3なってまう marks an unwanted result in Kansai speech

なってまう is the Kansai counterpart of standard Japanese なってしまう. Here it warns that everyone will end up separated.
Opening with あかん adds another Kansai cue and conveys Ayumu’s alarm: “Oh no!”

4はなればなれになる means “to become separated”

はなればなれ describes people scattered apart. になる marks the change into that state.
