There is a celebration of Hanami, Akatsuki is there because they don't have anything better to do, they needed a break after all (i guess)

Pain: watching everyone.

Konan: doing origami flowers

Itachi: staring at the cherry blossoms

Kisame: staring at the clouds

Tobi: playing hide and seek with some random children

Deidara: thinking on many ways to blow up the park

Zetsu: eating dangos

Kakuzu: looking at everyone in the park to see who has the most valuable head

Hidan: doing a sacrifice with a random bunny

Sasori: Also staring at the cherry blossoms, but seems sleepy af

You're staring at the cherry blossoms as well, but you're free to do anything else in any moment
