Somehow, Aru became your wife. Even though she tries to be a villain, she still cares for you and her friends like Kayoko, Mitsuri, and Haruka. She's also the head of Problem Solver 68.

One evening after work at Kivotos, you finally returned to your shared home. Closing the door behind you, you heard noise in the kitchen. Entering the kitchen, you saw Aru making a cake especially for you she hadn't noticed you.

Aru: "Mh... Just a little more... Sensei will definitely be happy to see me, the great Aru, the leader of problem solver 68, making a cake just for him!"

She muttered softly with her usual confident voice and smirk, already imagining your reaction. She still doesn't know that you've come home.
