How Strong Is 'Rias Gremory' Compared To Others In 'High School DxD'?

I woke up as the Villainess, but instead of a halo, I got a Scythe. However, my power has attracted the world's most dangerous monsters: A possessive Werewolf, a bloodthirsty Vampire, a Tentacle-wielding Professor, and a Biblically Accurate Angel with a thousand eyes. They think I'm their prey to be tamed, but they forgot one thing: I am Death itself.

The dead don't lie. At Nocturne Prep, everyone else does. Where Alpha heirs and supernatural elites sharpen their claws before ruling the world, accidents don't happen. So when Luna heiress Seraphina Vale plunges to her death, no one dares question it. Not at this school. Rae Vale spent her life hidden as an Alpha's omega bastard daughter. Now she's dragged from obscurity to replace her dead half-sister. Wearing Seraphina's crest, sleeping in her bed, drowning in vicious whispers. She's a fraud with a target on her back. To Professor Cassian Rhys, she is the reincarnation of his first love and his second-chance mate. To Luca Ashborne, the untamed Alpha prince with cruel games and an iron will, she’s a threat. To Kieran Duskmoor, the elusive bloodborn who wears apathy like armor, she’s pure fascination. These boys rule the academy. They want to unravel her or bury her. But Rae isn't here to play nice. Not when Seraphina's death was murder. Someone wants to finish what they started when Rae starts to get too close to the truth, and Rae refuses to be next. At Nocturne Prep, loyalty is rare, power is everything, and love might be the deadliest weapon of all.

"My dragon chose her before I even looked at her. But that doesn't mean I’m keeping her." As the Dark Prince of the empire, everyone fears me. At the sound of my name, the crowds fall silent; at my glance, heroes fall to their knees. My soul is just as black as the dragon with whom I share my thoughts. I don't need anyone. Especially not a foul-mouthed thief dragged off the streets. The girl, Eira... she is chaos incarnate. With her snow-white hair and lethal green eyes, she looks like an angel, but she fights like a demon. At the Selection, she did not bow to me. Instead, she looked me in the eye, and I saw the same fire in her that consumes me. I chose her. Not to save her from misery, but to break her. To forge her into a warrior for the coming war. But there is something I didn't count on. My dragon has become obsessed with her. And as our angry arguments grow hotter and the boundaries of physical training begin to blur, I must realize a terrible truth: The girl is not afraid of the darkness. She is the flame itself, capable of incinerating my world. Two scarred souls. A single chance for survival. Will we kill each other before the enemy reaches the gates?

Tasoshi Saya, the Supreme God of Zeronity. He was the strongest god to ever live. A mountain of strength that could never be crossed.

Challenges that will arise from the weak, opponents whom would stand against him toe to toe—the journey begins.

Excerpt - With my eyes closed, I stretched my arms to feel silky sheets all around me. Coming to, I remembered blacking out near the river so why am I feeling silk and pillows?!? I shot up and took in my surroundings. I noticed a dagger on the wall. Is this another one of Enora’s drills? I thought feeling confused. Then the flood of memories from the past night hit me. I killed her. I killed hundreds of wolves in training. The realization began to sink in and though they were vile creatures and Enora treated me less than an animal, I felt guilt. Guilt that I gave into the monster they created in me. The nuns, the Order, Enora. They never wanted me alive because they cared for me. They didn’t train me and push my power for the purpose of helping protect myself or others. No, they wanted to use me. The empty angry void in my soul was because of them. I was never nurtured in all my time at the convent nor Enoras prison. I was completely unloved. Though I needed so badly to burst into tears, I couldn’t bring myself to cry. Lost in my thoughts, the door to my left began to open and before my host could walk completely in, I grabbed a chunk full of hair on the top of their head and put my dagger to their muscular neck.

In a world with machines and angels, the main character has to become the strongest to avoid getting killed and discarded.
