WARNING; POSSIBLE SPOILERS AHEAD BECAUSE ME AND PRAE ARE ASSHOLES WHO WANNA RUIN YOU

Now this isn’t some comparing ONS to different Anime’s and Such thing but after talking with caramelbucks​ I think we’ve realized OwaSera has some Deep shit

Pretty much we’ve all been able to get the Seraph’s reference, which for those who don’t know, Seraph’s where the Highest Ranking Angels with Black and Red wings. 

In the Bible there where Two Seraphs in Particular, Lucifer and Michael. Lucifer was more known as the First angel and gods most beloved who became so overcome with jealousy he became Fallen angel who Became corrupt and Michael was known for being his slayer.

Now first We’ll start off by pointing out the reference with the Horsemen of Apocalypse, which in Biblical terms is the reference to showing the Apocalypse is near, which is already obvious in the story.

Now we’re going to investigate some name meanings. Note, I am in no way associated with any religion, so this is from an agnostic Standpoint.

Hyakuya means Hundred Nights, which for now doesn’t really have any meaning but is also a Derative of Byakuya, which means White Night.

Hiiragi means Holy or Holy ones. Which could be a reference to the “Holy Family”. And in the Light novel, the Hiiragi’s and Hyakuya Church where conspiring together, and since the Hyakuya Church was the one’s experimenting and Creating the Seraphs, so they’re pretty much The Creator [ God] and Hiiragi is the Holy Family closest to god.

Now let’s look at two Little Favourite Characters.
Mikaela and Yuichirou.

Yuichirou means “ superior first son” Which, in Biblical terms was Lucifer. And as most know, Lucifer was indeed, a Seraph. 

Mikaela is the Feminine form of Micheal which means “gift from god”, who was the Seraph who slayed Lucifer.

Think about it. Two Seraphs, Two Opposite sides. And the Human’s are being shown as the Corrupted and Tainted. 

Now we’ll investigate another Character; Guren, who may in fact be a reference to Gabriel, whom was God’s messenger and revealed the Prophecies.

So, there could possibly be a chance that indeed, It might Actually be Yuu who dies, and not Mika. And this may have been a foreshadow for the ending. And even if it wasn’t, oh well ~!!
