This is where you're wrong. The times where Issei has won fights alone is less than the fights he has won as a team. In fact, the only fight Issei has won alone is the one against Diodora and the second one against Shalba.

First, regarding the Issei vs Sairaorg battle, yes they fought one-on-one, but compared to Sairaorg who had to battle Yuuto, Xenovia and Rossweisse 3-on-1 prior, Issei had the slight advantage where he friends helped weaken Sairaorg prior.

"I wanted to use Ascalon and attack. But…….. With my low skills at using swords, it will be hard to give damage to that man who was covered in Touki. It was more effective to damage him in a fist fight I'm familiar with. While fighting, I also realised the abnormal movement of Sairaorg-san. The punch from his right arm was slightly slower than his left arm. It seemed like the impact was slightly weaker as well. Was that……?.. The injuries of having his right-arm cut off by Kiba and Xenovia showing its effect….? It couldn’t completely heal itself even with the Phoenix Tear?

-I will send you in front of the Sekiryuutei in the best condition!

I replayed the words said by Kiba."

So where's their credit on that? Or the credit goes to Issei solely because he was the one who beat him and the others don't deserve the credit.

Second, Issei fought Cao Cao alone?

"-Then I felt something. When I spread my wings to that direction, a single ray of crimson aura hits me and replenishes my aura. I then saw Rias on a building far away who shot the Oppai-beam to me. Aaaah Rias! You made the size of your oppai smaller again for me! Rias’s love for me feels very supportive! The power I received from the woman I love! There isn’t any power stronger than this! I even sensed her thoughts without even planning about this. Rias and I must be connected deeply from our hearts! It sure makes me happy!

“The beam from a breast that I heard rumours about. I see. You couple are really terrifying.”

Cao Cao says that while laughing!"

Now this is one of the case where i say, Rias wasn't given credit, yes she didn't involve directly in the fight, but she did support Issei, where's her credit on that? Or are you trying to say once again that since Issei is the one to beat him only Issei deserves the credit on that.

Third, the one against Euclid yes he was fighting Euclid 1-on-1 for a while where he was getting beat up until a last minute power-up, even then he still couldn't beat Euclid and would have lost if Gasper didn't come back him up. Plus the fight only ended because Rizevim ordered the retreat. If the fight continued Issei would have undoubtedly lost.

"《I can’t endure having the power they attained from Valerie being misused any more than this.》

Gasper the Beast of Darkness catches the sight of Euclid with his eyes.

“Yeah, you sure are right about that!”

I also make my stance since I have the same opinion. My stamina will run out soon so I won’t be able to maintain my armour, but our victory won’t change if I have this Gasper with me.

I will defeat him and capture him. I’m going to prove Grayfia-san’s innocence by sending this guy to the Underworld!

Gasper and I try to go at him, but—

“Euclid!”

It’s the silver haired man who is coming our way—Rizevim Livan Lucifer."

So where's Gasper's credit, where's Ddraig and Albion's credit which open up a new power-up possibility for Issei?

All that being said, Issei isn't some super OPed MC or some MC who fights his battle alone. Issei is a type of MC who depends on his allies as much as they depend on him, and they function together as a team to defeat their enemies. If it wasn't that way, everyone in the ORC would've lost their role in the story a long time ago. With characters like Vali, Sairaorg, Yuuto, Gasper and Dulio around. Just those 6 teaming up together and others can just stand aside and do nothing.
