Shadow monarch in DXD (Male ocxcrossover)

Chapter 1: The test

Time Skip (9 years later)
(POV, Dante Ashborn)
It had been 9 years after I started my hellish training with Ashborn. In the first 4 years, I had been doing exercises to enforce my body so that it would withstand the power of Monarch of Shadows. Afterwards, until today the training was constant sparring with Ashborn, when I asked him why he always fought with me personally and he said the reason was that he was my teacher which meant he was the one who had to train me. Also, I was raiding low level dungeons to get some fighting experience.

Yesterday was a relaxing day for me. My grandfather told me that today would be my final test, and if I passed, I would finally inherit his legendary power. All he told me was that the test would be divided into three parts.

As I wondered what the test would be, my grandfather came into my room and told me that we would start exactly at 12 o'clock. I looked at the clock on the wall and saw that I had 15 minutes before the test. I was also told that I couldn't use any equipment, so the only thing which I could do, is mental preparation for the exam.

At 11:55, I went to the training field where the test would be held. Exactly at 12 o'clock, I saw two figures appear on the other side of the field. They were two generals from my grandfather's shadow army, Tusk and Greed. I assumed that the test would require me to fight multiple opponents with good balance and chemistry.

Even though I didn't see any shadows in the action before I knew for sure that they shouldn't be underestimated even the weakest shadows of the normal rank, so I quickly took a defensive stand, but before we started, I asked my grandfather a question.

Dante: grandfather, before we start, can I ask you a question?
Ashborn: Of course!
Dante: thank you! How should I know that I passed this part
Ashborn: good question, you have to defeat both of them. They are shadows but they still can be damaged and if I consider the damage made by you on them enough, you win. Also their physical and magical abilities will be reduced to your level so don't worry about them easily overpowering you.
Dante: Okay then, let's start.

After I finished speaking, Greed rushed at me and tried to punch me, but I dodged by jumping over him. Then, I rushed to Tusk because my grandfather had taught me that mages could be very dangerous in team fights and needed to be eliminated. Tusk was capable of debuffing and attacking with dangerous magic. While I was running towards Tusk, he conjured several fireballs, but I easily dodged them. When I was in front of him, I faked a punch, jumped in the air just above his head, and punched him in the face. As a result, he was eliminated, and only Greed was left.

Even though Greed was a strong opponent, my superior martial arts skills allowed me to defeat him easily.

Ashborn: Good job! I didn't expect any less than that from you. For now I will let you have 5 minutes break before we proceed with the next part.

Dante: I am not tired so we can go directly to the next stage without rest.
Ashborn: Okay

I saw how Greed and Tusk disappeared and one of the shadow marshals appeared instead of them. The legendary dark night Igris. So the next fight would be a fight against a knight. I knew that this would not be as easy as against Tusk and Greed who were not strong in martial arts especially Tusk, now I had a swordsmanship test against a knight with nearly perfect sword skills and much more experience than me. While I was thinking, my grandfather started to explain the next part.

Ashborn: your next fight will be against Igris. The test is made to evaluate your swordsmanship skills and to make it the test of swordsmanship, Igris will hold back to your level of power. Also both of you will have the same swords which were made by my powers.

Next second I saw how a dark sword appeared in my right hand and the same appeared in the Igris's hand.

Ashborn: your goal is to hit Igris by sword at least once then you will be declared as a winner, I will allow you to continue to fight until you are able to, if you lose a sword a new one will automatically appear.
