 If you liked Lv1 Maou to One Room Yuusha |  ...then you might like Sasaki to Pii-chan |
Both of these anime: -made by Silver Link Studio. -fantasy/magic element blended with action and comedy. -features a middle aged protagonist. -cute mascot that was once a powerful entity. -government organization that wants to combat the disruptions and wants to recruit the MC. -stalkers. -young girl has "crush" on the middle-aged MC that will make you raise your eyebrows. Both anime overall has similar vibe. While Lv1 Maou is more laid-back, Sasaki is similar but has more serious undertones. If you like one you'll most likely enjoy the other.
