Things that I find similar are like previously said the fact that there's a demon inside the main characters (Naruto = Kyuubi // Jio = Satan) but the difference is that the Kyuubi isn't as cunning or "free" as Satan is. Kyuubi just pours out chakra and makes physical manifestations when the seal becomes loose while Satan gave Jio a double-edged sword (the power absorbtion power) and has full control when possessing the host, unlike the mindless Kyuubi. Also about the eye technique users I don't see that as an issue as the Cyclops people have telekenesis which is comes from a 3rd eye in the middle of their forehead, completely different from Naruto's byakuugan and sharingan which are visual enhancement/ illusion inducing.
Kirin resembles Urahara in the sense that he lives as a hermit now but was/is a powerful warrior, plus the fact that he mentors the main character.
Ruby is strange because to me she seems like a really strong character, which seems like a new concept for a female character (before she had her Angel powers she was really strong willed, now she's battle-strong too)
The Final Fantasy aspect is from the fact that there's been a long-term mission (Capture the demons/angels and defeat Zenom/Stea) and the fact they have an air ship
