Crossover ORI no Monogatari

my first crossover story! XD
It's the combination from much much n much~
1.Roxis Rosenkrantz: Mana Khemia (As leader and strategist also an magician)
2.Jaster Rogue: Rogue Galaxy (as main attacker)
3.Oreki Houtarou: Hyouka (can't fight, but as extreme strategist)
4.Ainsel Tachibana: OC (as Oreki's bodyguard, long ranged attacker)
5.Kain: Radiata Stories (just a middle chara, as a god who destinied those 3 to do a journey)

Antagonist:
1.Ayatane Michitaka&Kureha: Ar Tonelico 1-3 (Boss and main troublemaker, Roxis' enemy)
2.Akira: Samurai Deeper Kyo (the ice element user, Jaster's enemy)
3.Arnaud G.Vazquez: Wild Arms 4 (the great strategist, old friend of Ai, Oreki & Ai's enemy)

Preview: The Galaxy is in trouble on Hymn Planet (the planet of Song/Hymn (Ar Tonelico's land)), the Viruses has spreaded in all over the galaxy..And the one who did it was Ayatane, the son of the Virus..Then Roxis from Alborus planet (Alchemist Uroborus) want to try Muppy's Galaxy Spaceship III, but accidently started on and he crashed into a strange Desert planet, Rosa and met Jaster. then in order to repair Roxis' spaceship, they need to find at least 2 person at planet Earth, and they're going to Earth then meet with Oreki and Ai. but Roxis change his mind and keep on journey with them.
On the journey, they must learn 3 songs/hymns to open the gate to Hymn planet and destroy the enemies there..The 1st hymn they learn is EXEC_FLAMENZA, sang by Ainsel and Oreki. the 2nd is EXEC//.CHRONICLE KEY, sang by Ainsel, Oreki and Roxis. Jaster the only one who can't sing hymn, but when at Rose Nebula, Star King and Kain appear and blessed him with power that can sing hymn. And the last one is METHOD_REPLAKIA, sing by those 4 to open the gate to Hymn Planet.
There, they fight their own enemies and the ending...
