My Dress-Up Darling
Sajuna is impressed by the concept that he emails her and gives him her sister's camera after he says that he wants to learn how to properly take photos. They all meet her Shinju, sister at a dinner and she teaches them photography. They have a photoshoot at an abandoned hospital for Sajuna's outfit. Wakana shows up to the shoot with Shinju and both Marine and Sajuna are surprised to see her in a cosplay outfit.
