Mahiru-no-Yo/Relationships

Mahiru-no-Yo interacts with various other characters throughout the Seraph of the End series, which affects themselves and the story. This article details Mahiru-no-Yo's relationships with other characters.

Guren Ichinose
Mahiru's lover before becoming his sword. Guren treats her coldly, often ignoring or silencing her when she speaks to him. However, in some cases he talks to her intentionally, just to kill some time or gather information out of her. At first he believed her nothing to be just a fantasy created by Noya, until he found out that she represents his desires.

With her demon and human side merged, Mahiru retained her love for Guren as Mahiru-no-yo and she is delighted whenever Guren chats with her in his mind. Although not above taking control at times, she mostly allowed Guren to do whatever he does. She manifests quite often when Guren mentions her or Shinoa, much to her happiness which she sometimes complements him, though he ignores her. Indeed, Mahiru went as far as to comfort Guren in her demonic form, willingly shouldering the blame of causing the Catastrophe along with him.

Shinoa Hīragi
Mahiru's sister. When she hears Guren invoke Mahiru-no-Yo's name, she confronts him and asks him if he is in control of Mahiru-no-Yo or is she controlling him, which he denies this fact as he is in control. She is still angered at the fact that her sister is within Guren's sword and is convinced that he killed her, despite it being the latter.

Noya
Guren's previous demon that Mahiru gave to him. She stabbed herself and fused with Noya to become Guren's demon. However, Noya managed to erupt from Mahiru-no-Yo's demon body, meaning he did not completely disappear after he was merged with Mahiru, and Guren was able to call his name as well. If both are separated, they turn Guren into a namanari but him in control. As well as Mahiru-no-Yo body turns into a spirit form.

Byakkomaru
Mahiru first meets Byakkomaru when Guren's Squad was heading to Osaka. He manifests in front of Mahiru-no-Yo and confronts her, he is cautious of her since he can tell she is not a demon. He threatens her if she tries to harm Shinya, which Mahiru silences him and ignores the warning. Mahiru likely thinks lowly of Byakkomaru because she calls him a beast.

Ferid Bathory
A seventh progenitor vampire who has been working with Mahiru for quite sometime. However, upon becoming Guren's Cursed Gear, Mahiru knew Ferid would approach him and use him. Thus, Mahiru-no-Yo ordered Guren to kill him and she is not above possessing him to do so. She sees him as someone who gets in Guren's way as she is the only one who Guren should listen to. Upon learning what happened to Mahiru as she became a demon, Ferid is amused by this fact, and he leaves them alone.

Saitō
The leader of the Hyakuya Sect, and a former second progenitor vampire. Prior to becoming Guren's Cursed Gear, they worked together in the Hyakuya Sect. She seems to have no memory of him after becoming Guren's sword. However, Saitō knows her and he knew why she became a demon. Furthermore, he throws a sinful key at her neck, which according to him he hid a sin.

Krul Tepes
Mahiru-no-Yo would tread close to where Krul was and saw that she was being guarded by Ky Luc.

Ky Luc
Finding this fifth progenitor monitoring the sun exposure torture that Krul and Ferid are weathering Mahiru assesses that he is right that there might be a ghost. Whilst she cannot be seen something about her can be detected. Knowing that he was there and appearing in the road before Guren caused him to change his path from where Krul and Ferid were to heading for Ferid's manor where Shinoa squad was situated.
