EPISODIUM
The girls decide to go on a hiking trip one day, and as they participate, they meet one of Hana's sister Kotori's classmates, Aisaki Emiru. She is seen always being super prepared and cautious for anything. However, her concerns cause more harm than good as she winds up accidentally destroying a footbridge with her hammer among other things, putting the group in more danger. Then, to make matters worse, a monkey makes off with the Melody Tambourine, causing Hana and Emiru to go on a chase after it and as a result, they fall into a pit. Will they be able to get out if it?
