Capricorn Ionia

Ionia was the Capricorn Saint in the Century XX and another centuries.

History as a hero
Ionia was the capricorn saint in various times but, retired from his office. After the war against Hades in the XX century, Ionia saw Athena's suffering (he hates this, and in the future, will motivate him became a villain), so, decided help her, althought he have been retired; he founded a school of servants of Athena, but the hard training causes a rebellion, forcing Ionia kill his students. Ionia never forgive himself, and arrested himself in a prision, where months (or years) elapsed. Athena forgive Ionia personally, and ask to him turn back the Capricorn Saint and turn the principal of Pallaestra. Probably, Athena and the other Saints like Shun and Shiryu, stay hidden, helplessy because of them darkness hurts.

Villain
When Mars knew about office of Ionia, propouse to him the papacy of new Sanctuary, in exchange, to manipulate Pallaestra students to serves him. Ionia accepts, because he want the end of Athena painess in the world. He invites Harbinger to became a Saint. He was the most featured Saint of Mars, because his old age and because he always appear as a involved in the story of the another saints, representing Mars.

As Pallaestra principal, Kouga got admiration to him, but, when Kouga invades Athena's room, discovery that Athena, is not the Athena who he met... he is Aria, and Ionia uses his darkness cosmo to brainwash she (to think she is Athena).

The time to capture Pallaestra students has come, and Ionia helps Mars to arrested them in a coffin made by Schiller.

In Capricorn Temple, Ionia fights with Kouga, and his story don't convinces him, and, althought he rejuvenates, Ionia is defeated by Kouga.
