Having swum from the mainland alone and without any possessions, he enrolls in the senior high level in the school on the island – Southern Cross High School.
With his bright and positive personality, he starts to mix with various students in the school and builds relationships with many of them, including Wako Agemaki and Sugata Shindou. But this school hides a deep secret. There are sleeping giants hidden under the ground called “Cybodies”.
There are about 20 of these giants, and they are just some of the various secrets kept by everyone on the island: The secret movements of the mysterious organization known as Glittering Crux. The songs of the shrine maidens. And even Takuto himself will soon come to embrace a great secret…
This island in the southern territories surrounded by the blue sea and the blue skies is the stage where the “Eulogy of Youth” filled with love, dreams and friendships, will begin.
Renton Thurston is a 14-year-old boy who lived with his mechanic grandfather in a backwater town. Every day he dreamed of being with the mercenary “Light Finding Operation (LFO)” aircraft pilot group “Gekkostate” and riding “Trapar” particle waves—a sport called “reffing”—with their charismatic leader Holland, especially when faced with his father’s acclaimed past or his grandfather’s desire to protect him. When a young girl named Eureka riding the original LFO, the “Nirvash typeZERO,” asks his grandfather for a tune-up, she inadvertently brings the attention of the military to the garage; as a result, the garage is destroyed and Renton is forced to deliver a new type of interface—the “Amita Drive”—to the Nirvash. After a heated fight in which the Nirvash destroys the military LFOs by unleashing an immense amount of power, Renton is invited into Gekkostate. However, he quickly realizes that behind the facade of a traveling group of mercenaries is a very bitter reality.(Source: ANN)
In the year 2015, the Angels, huge, tremendously powerful, alien war machines, appear in Tokyo for the second time. The only hope for Mankind’s survival lies in the Evangelion, a humanoid fighting machine developed by NERV, a special United Nations agency. Capable of withstanding anything the Angels can dish out, the Evangelion’s one drawback lies in the limited number of people able to pilot them. Only a handful of teenagers, all born fourteen years ago, nine months after the Angels first appeared, are able to interface with the Evangelion. One such teenager is Shinji Ikari, whose father heads the NERV team that developed and maintains the Evangelion. Thrust into a maelstrom of battle and events that he does not understand, Shinji is forced to plumb the depths of his own inner resources for the courage and strength to not only fight, but to survive, or risk losing everything.
