The cool, beautiful Hikaru Tsuki shows up at Tozai Academy's elementary school as a new teacher one day. But her true identity is that of a Peacekeeper-and princess!-from the planet Alpha, dispatched to Earth by the Andromeda Branch of the Space Alliance. She secretly investigates the earthlings while living among them under her assumed identity. Aside from her research, she uses the mystical powers of her Moonlight Ring to help the people around her with their problems. With her guidance, even sworn enemies turn into friends-but her eagerness to help sometimes leads to even more trouble. Joining her in her journey are an ensemble of zany, outlandish characters, including her assistant Baru, and the many monsters and oddball villains who regularly show up to wreak havoc.—Toei Tokusatsu World Official

Suki. Suki!. Majo Sensei ("Love. Love!. Witch Teacher") is a 1971 Toku comedy series. Hikaru Tsuki is a new 5th grade teacher at Tozai Elementary School. Secretly, she is also the alien princess of Planet Alpha and a peacekeeper for the Space Alliance assigned to Earth. The first 13 episodes are mainly comedy-focused where Hikaru would use her magical powers to help her students with mundane issues. Midway through however, Hikaru gained the power to become a superheroine named "Andro Mask", resulting in Majo Sensei being the first Toku show to feature a female Henshin Hero. From then on the show became more action-focused, with Hikaru repeatedly doing battle against a recurring Arch-Enemy in the form of the blood-sucking alien Kumondes.—TVTropes
