Just to give and idea of the New angel in the story, here is some Info
Iaito Alonne Reaper- Fallen Angel Prince
Iaito is the protagonist of the story and the Lover and husband to Granberia, and the father to Blizzard, Alleyne, and Granderia (Named after her mother, just spelled different, all of which are half Angel/Dragon/human). At the age of 313, he is the son of Queen Hilinia, and the son of Sir Alonne (Making him a Half human, and half angel, similar to Lukas Gender), Iaito is a male, about 5.9 in height and only weighing 125 pounds, His has a slim figure with Black and red hair tips hanging off the tips of his bangs that fall short on his right head. He is also the owner of both Bewitched Blade, and Calamity (Sword of Hades, and both Katanas)
Iaito is one of the Main protagonist of the story, but other than that, he is the main focal point of the story, during his time living in the underworld, he was 13 before sealed away by the fake angel Ilias, awakening from his slumber, he is over 313 years, old looking the same as he was when he was 13. He hails from the royal line of the fallen angels of the first period of the first monster lord, and is the son of the Fallen angel queen: Hilinia (Pretty much the Angel ghoul that luka encounters in the game). His is also the son of the infamous Ronin and samurai god Sir Alonne, the Bewitched Samurai. Hailing the powers of both the Angel and God like demonic powers, it is impossible to see who is stronger between him and Luka, since both hail from two and unusual powerful parents, but Iaito proved that he was stronger by saying that Luka is afraid to open his limits of his angelic powers, Luka then tried to prove him wrong, for he did not want the other monster see their king a weak and helpless king.
Iaito is a special case when awaken from his slumber, due to the fact that he was sealed away, he was awaken with a split personality, having one as a cheerful, shy, defenseless, scared, and smart Iaito. While his other personality is very aggressive, mean, rude, powerful, evil, and brainless maniac (Stated by Alma Elam and Erubetie), and has a very big appetite for food (Mostly Meat).
The softer side of Iaito is very kind and very happy Iaito, who looks after children during the story, always telling them everything was going to be alright when a huge earthquake took place in Ether village, he is very dependable upon knowledge of both Humans and Monsters, He even found a way for the Slime colony to live in polluted waters with the power to cleanse in a mere second, this led Erubetie to start falling for Iaito. Due to these properties, he is left with only being shy and defenseless in dangerous situations, but starts to act a little more braver when children lives or females are in harm's way, He is one that everyone in the story can actes upon when needed.
The Aggressive side of Iaito is very Evil and Mean, when he is protecting other people, he actual shoves them to one side and not care what happens to them, going all out on any opponent, or any ally, he is bloodlust for battle and will do everything to win, during his encounter against luka, he goes berserk at the powers that Luka had, matched the Ilias imposter from his past, that killed his mother and his masters and overtook his kingdom in the Underworld, soon after Iaito beats Luka, he raises his weapon attempting to kill Luka, Luka then had no choice but to use "Quadruple Giga", but even that did not stop Iaito. After his last resort, the four Heavenly knights and Alice the sixteenth and his wife came to his aid, Granberia instantly recognized Iaito as she was beaten by him and Crown city's Battle Royal duel, she marked Iaito as a rival and a worthy warrior of respect, battling and defeating him, all six including Luka converge on Iaito and pinned him to the ground, Alice using her magic put him to sleep and he was taken to Hell Dongo for further questioned, this mark the relationship between him and Granberia to build. Although Iaitos Aggressive side is ruthless, he laters in the story starts to have feeling towards Granberia who too had feeling for him later, this mark his changing his ways of protecting his comrades and other people in need of protection.
