• Strikers are high technology machine made around World war II era for witches to fly. Only witches can use them & for some reason they are all female witches.
• It's possible to made a machine which is capable to produce a magical shield to protect their user from attacks & danger if the user is a witch.
• When you join an army & engage in war, it's better not to socialize with any men or you'll be fall in love than feel the pain of losing them in war.
• Little girls under 15 yrs old are capable for carrying heavy guns & shooting so well with them while flying. They just need to activate their witch power
• When witches use their power their animal ears & tails will come out and it only happen to female witches.
• Witches cruel fate is, when you reach 20 yrs old your power will declines like Sakamoto Mio, and our power will reach it's peak while they are still young teenagers that's why strike witches members are all young teenagers.
• Walking around or traveling with only wearing a pants underwear & tops worn on the upper half of the body is totally normal and no pervert guys will ever stare at our bottom!!
• Another point about only wearing pants for our bottom is no need to worry for the cold weather either because our bottom won't feel cold. We also won't catch a cold from that! Totally safe!! No need to be afraid that while flying on the sky the wind will blow our shirts up and uncover our body, hips & butt !! Again, we also won't catch a cold from that. :D
• Borrowing other girls' underwear is safe even after they are just worn by the owners. No need to be modest.
• Wearing a swimming suit under a shirt everyday, whenever or wherever you are like Yoshika is normal. Moreover, it's also exist as a uniform for school

just for your information it's really not comfortable at all!! not only it's tight & thick, it mades the clothes we are wearing outside of it feel so slippery!! you know swimming suit is tight at the thighs part. no one will wear it everyday, everywhere, even when we are traveling!!!
• No need to change pants or clothes wherever you are except when you are sleeping. Even when you stay abroad or travel it's okay to only wear a school uniform and the same pants all the time. no need to bring spare ones. You can also wear them when you are in the Army squad.
• There's a country in the northeast Europe, named Suomus, where people love sauna more that bathing. I don't get it. Even more than a nice hot water bath in a tub??
I learned lots of weird things by watching this anime. Any other ideas?
