I took Naoya's route the first time. Had to level grind forever to beat the Bel gauntlet. But my super powerful Culebre (who I have seen every ending with he is so precious. He has Mediarahan, Mabufudyne (or Ice Dance as I sometimes shift it for bosses), Drain, Victory Cry, the obligitory Ice Repel, and Ice Amp.) beat the crap out of everything :3
