聖少女戦隊レイカーズ

Akira Daidōji was just an ordinary teenager until one night he had a strange dream. When he woke up he was contacted by a mysterious stranger from another planet who told him that the Gadram Empire is attacking his homeland because they need the power of the so-called Laker Crystals to survive. Akira was chosen as the next guardian of the crystals. In order to defeat Galvan, the dark leader of Gadram, Akira has to discover five young girls with special powers and assemble a team for the upcoming battle.
