The Pisces Spirit King [Anime Crossover]

Qi Feng Liuzhi, the third Spirit King of the Soul Society, reigned for 759 years. The Hollow King, Gargantua, invaded the Soul Society with a host of Menos. The Thirteen Court Guard Squads suffered heavy casualties. After the Spirit King used the power of the three great spirit weapons to seal the Hollow King, he died of his injuries. His royal blade, the King of Broken Cocoon, was enshrined at the Sogyoku Hill in Seireitei. Before an ancient, tranquil Greek sanctuary, a peerless young warrior clad in golden armor slowly fell to his knees in a pool of blood as red as roses. The ground was strewn with dazzling, bewitching blooms, and amid the scarlet, a sacred glimmer of gold formed a scene of breathtaking, tragic beauty... "Albafica..." The bells rang from the Pope's Hall. Seeing the beautiful body of his comrade lying cold and lifeless, Aries Gold Saint Shion's eyes dimmed, and he silently lowered his eyelids. More than 200 years later, a baby was born, breaking the destined path of fighting for the goddess. The Hollow World has original worldbuilding. The male lead is a Pisces Saint Seiya named after the God of Beauty. It's too hard to choose a pairing, so I'm letting readers pick their favorite. Options are listed among the supporting characters.
