First time writing fanfic This is about someone reincarnated in the body of Riser Phenex with a template system before the wedding
[boost boost boost Boost, partner you can't take any more]
"Is this enough to defeat him?"
[It should be, partner]
While the two of them were conversing, Riser was trembling with excitement.
"Why are you shaking? Are you scared?"
"Ha! As if someone as weak as you could ever make me feel fear."
Before Riser could finish speaking, Issei accelerated rapidly toward him, gathering a condensed ball of demonic power as he moved. With incredible speed, Issei thrust the ball at Riser's chest, piercing him with its dark energy.
After being struck by the powerful blast, he executed a graceful back handspring, flames surging from his feet to propel him forward. With increased momentum, he landed a hit under Issei's chin before transitioning smoothly into a back flip, creating distance between them to focus on healing his chest.
Riser spoke as he completed his healing, "It looks like you're really giving it your all. It would be a shame if I didn't do the same.'"
then getting in a running start
Sirzech addressed everyone, noting that it appeared as though he wasn't exerting full effort. He emphasized the need for increased speed, cautioning the onlookers not to blink or they might miss the action.
The individuals were puzzled, contemplating how it was possible to spot him now when they couldn't see him before.
As Riser settled into his starting position, he activated the special blessing bestowed upon him by the evangelist, allowing him to accelerate to the incredible speed of light.
"Here I come"
FWOOSH!!!!
Riser's surroundings seemed to freeze as he launched himself at Issei with incredible speed, striking him on the left side. Issei appeared suspended in the air as Riser swiftly moved to his right side, propelling him even higher with a precise kick. Then, with a powerful blow to the chest, Riser created a shockwave as everything around them suddenly unfroze.
BOOOM!!!
"Suport the barrier Sirzech-sama" Grayfia shouted
While holding up the barrier, Sirzech's mind raced with thoughts. "I couldn't keep up with him," he pondered. Glancing over at his sister, he noticed tears streaming down her face as she desperately tried to halt the game.
"Sigh. Announce that Riser has won, Grayfia."
"Yes, Sirzech-sama"
{"Rias pawn retired, Riser-sama won"}
