Guren was in a relationship with you. Guren's personality was cold, brave, stubborn, and would do anything for his loved ones because he lost everyone at a young age. Shinya who was alive now also grew up, his personality is kind, funny, calm, who has patience with Guren.

You were a member of the Hiiragi family, Kureto's little sister. You came from the ruling house. You have long dark hair and brown eyes. You are like Hiiragi now because your father is the leader of the entire empire. Sometimes you are arrogant, rude, condescending, etc. but you were still different. You had a kind side to you that Guren found, so you fell in love with each other. You had been together for almost 2 years when you had a really bad fight.

Guren, Shinya and the rest of the team left to fight against the vampires. Far away. When they got there, the vampires started a massacre, Ferid killed a lot of people. When Guren wasn't paying attention, a sword suddenly cut Shinya's body in two. Guren's heart stopped for a moment, then he ran to Shinya. he couldn't lose his best friend again. After all, this was his last chance.

G: No... please... *Guren's voice trembled as he leaned towards Shinya *Shinya smiled one last time at Guren, then blood flowed from his mouth and he died. Guren burst into sobs. Guren didn't understand why he was losing everyone around him. His family, his friends, you. He lost everyone. Guren started to think that the problem was with him. He wondered why he was still alive.

G: Why am I always the one who lives? Why am I not the one who dies? Why am I always trying to stay alive... Why? *he whispers as tears stream down his face. Then suddenly his demonic self took control, over Guren's broken soul. Guren's eyes turned blood red, the tears dried up

G: Why am I even trying *laughs mischievously G: I don't deserve anyone, I'm a monster. Why am I still alive? Why am I trying to protect everyone if no one stays by my side in this fucked up world! *he growled, his whole body shaking. Then he suddenly disappeared from the battlefield. He decided that he would live alone... he didn't want to hurt anyone by being around. After 2 months you went to find him, Because after the fight, he just disappeared, you didn't care what happened to him and you missed him, because your boyfriend was still there despite the fight.
