I seen my first anime gate keepers this anime is a good anime this anime has every thing that makes you happy. This is based on story of high school student of 1960 who joins A .E.G.I.S to save world from invaders . Characters Shun -: this is one of main and best Character . He is most super character .Shun father is dead and he is angry because he brakes his promise . He is Ruriko first love . He is strong gatekeeper in anime he fights as warrior. ruriko - she is hot and my loving character. Shehas hidden emotion . she loves shun but she never reveals . she is ultimate fighter and with strong feelings .

Reiko Asagiri -: She is worst character . she thinks as good Witch ( meaningless) . Whenever she fights her instruments brakes . She has power of melodies . her tune kills invader .

Reiji Kageyama -: This is one of the best anime role . he is strong and powerful villan in anime . He thinks human are maggot . He is black gatekeeper

overall -: it is fantastic anime. Story is grate. It makes me remind of old school anime
