This makes sense. I grew up with a brother and I would never have given him the ability to unlock my phone. The omnipotent older sister character reminds me of Chizuru from Shinryaku! Ika Musume. I am ~1/3 the way through this series, but picked it up after realizing it was the same author as Atsumare! Fushigi Kenkyu-bu. It’s been a lot of fun and similar sense of humor in both.
