User blog comment:AquilaeAltair/OnS Theories. Third Theory (S3) - The reason of Guren's betrayal/@comment-36009152-20190703020437

An exceptionally impressive number of theories so far! It is the case that whenever we think the manga is coming to tie up a loose end, it instead branches even further. Think Asuramaru’s memories are going to give Yu something to help Shinoa, they show that Sika Madu and Yu had seraph powers during the dark ages of Greece, fascinating and all yet the overall bearing on the plot has yet to be shown. Seems a straightforward direction with everyone fighting against the invading Hyakuya Sect, Guren’s now betraying everyone, Yu has been ‘rescued’ by said invading Hyakuya Sect led by Saito, all we can predict is Kimizuki will be in the way when the Imperial Demon Army wants to activate their seraph. We cannot predict how Guren will betray, anyone could be first but this theory is ideal for suggesting why. You are right it is fascinating, in a horribly no way can this happen type of way, and that’s before Guren has even made his move! Hope these are not famous last words if he does something not acceptable, Shinya and Guren’s squad are nearby so do not want anything unthinkable to occur, ‘betraying’ Kureto is long overdue mind.

It is a testament of Shinoa’s character, that she all out supports Guren’s moves against her own Hiragi family and the friendly rapport she maintains with him. Yet she did not hesitate to pull a scythe on her army superior when he invoked Mahiru’s name and even debated with her own squad on whether to even side with Guren (unless she was just testing to see how they would react). Even worse with Mika with all he knows and yet it falls on deaf ears, feel really bad for Mika indeed. Interesting case where even though Mika has a point, the squad may remain wilfully blind to Guren’s actions since he is their commander and they are human and stick together because of that, possibly.

Just to share some considerations for Mahiru-no-Yo’s plans, yes they are no doubt tied to the highest order of secret plots, yet will restate here how her end goals may have changed with Noya’s desires now being in the mix. What she had planned as Mahiru could have changed with the transformation into Mahiru-no-Yo. Who knows, maybe Guren is sticking to a plot he planned with Mahiru, but Mahiru-no-Yo has something completely different in mind and nudging Guren towards that.

Love the part about leading everyone to their own end. With the Hyakuya Sect attacking would have thought Guren meant betray everyone and go to Saito’s side now that he is here, but Saito himself may fall under the betray everyone classification. Certainly prefer restore the world but at what cost remains to be seen, do not want it at the cost of his own life though so hopefully Guren is not after finding peace by way of dying. If he is hope someone stops him!

Hearing of Guren’s intent to betray, whether because of Mahiru-no-Yo, Guren can spirit over the red line, key point of attacking his own allies and the whole attacking Yu with a sword thing. Yet what he endures to keep people safe is the other extreme and makes it all the harder hearing of his intent to betray. It’s unfortunate at this point in the story that clearly there is something so pressing that Guren feels the need to carry out a long betray all plot, backed by the no-Yo. At any rate if there is an actual way to deal with any of the major threats of the series in the Shikama Doji, and really Hiragi family vein (really not a good idea to let them inherit the world) then Guren should, well actually he is taking the chance, but hope it doesn’t cost him or his close ones lives.
