Now it's Checkmate - High School DxD x Code Geass: Lelouch of the Rebellion

Forcing Your Good Intentions On Others...

...Is No Different From An Evil Act.

"The greatest battles in history were those where forces fought against all odds, Agincourt where 3000 Englishman defeated over 30,000 french cavalrymen.
Rorke's Drift where 150 Britannians defended against 3,000 Zulu warriors and won.
The Battle of Okehazama where an army of 30,000 strong fell to an army of just 3,000.
The Battle of Gravia Inn where 120 Greek Militants defeated 8,000 Ottomans.
And who could forget Thermopylae ? The Greeks may have lost but they stood till the last man.
We face a similar situation now centuries, decades, millennia later. Outgunned, out manned, no place to retreat. No reinforcements. But let those battles be remembered, in your heart and in your gun.
We will not give up! And even if, which I do not believe for a second, that we lay in chains and are subjugated. Our allies in Europe, in America, In Australia shall continue the fight Until one side lay defeated.
But As long as we fought. With everything we had! Then that's what counts! Against all odds! We faced an enemy, not fearing for our lives! But to give them! Let the children who be born after this day look not at us as terrorists! But as Martyrs! Upholders of Truth! Freedom! And justice!
Strike hard! Don't give in!" The soldiers raised their guns and cheered. I ascended the ladders of my Knightmare and entered the cockpit. What I said wasn't necessarily wrong. We had sixteen Knightmares left and only six of those were capable of flight. The enemy had near one hundred Knightmares. While they also had scarce numbers of flight enabled Knightmares theirs were more powerful than all but one of our Knightmares.
The Doom Slayer. We also had to deal with the Avalon and the Longdan. Alongside any aircraft or tanks.

The Chinese were firing on us and as predicted the Britannians are only providing aid.

"Identity confirmed, good evening commander." The computer said as I took off my helmet.
"Tohdoh, our flight enabled units will follow behind me, we'll spearhead an offensive against the airforces while our ground forces hold back and draw fire from the other Knightmares." I explained.
"Roger." He said as our Knightmares left the hangar bay.
As we ascended into the sky the whole battleground lit up and shook every second second. It was beautiful like watching live action art. There was about three dozen helicopters in the air. Easy prey.
"Remember our air power is limited ride with honour and strike like steel!" Tohdoh said to the remaining members of the Four Holy Swords.
I captured a homing missile in a stasis field and fired it back at the helicopter that shot it.
"Knights of the round coming in hot!" I reported under fire from the Mordred.
Chiba and Asahina decided to attempt to go after the Mordred even though they were both in Akatsukis. Oh well it's their funeral. Suzaku was against Tohdoh. I respected Tohdoh enough to let him have the fun with the Lancelot. It also appears that C.C has entered the battlefield and was helping Tohdoh fight the Lancelot.
I'm going after the Tristan and the Shen Hu. They were both attempting to take each other out, no surprise there. Xingke was loyal to the Empress.
I slammed into the Tristan, firing my 20mm rounds into its float system.
"Oh it's you again? Well I've had a little upgrade." Gino stated smugly he fused the Knightmares arms together and fired off something, i went flying back.
"Computer! What is that!" I ordered.
"It seems to be the result of nuclear fission reaction enhanced by Sakuradite. Tread lightly Sir." The computer said.
"Ah well two can play at that game!" I shouted down the intercom creating the same weapon that Gino used. Albeit much less powerful as I only had what the computer gave me to go on. I fired it but the beam was too slow.
"What?! How did you?!" Gino activated his shields.
"A little birdie told me!" I lied. It would create further disarray and cast suspicion upon certain individuals.
"Give the empress back now!" Xingke stated. I turned around but it was just too late, he brought his sword down onto the Doom Slayers arm, shattering it. I hypothesised he used all its power to deliver that blow.
"Why don't you go get her? Computer! Activate regeneration sequence!"
The same pain I felt when the wrist was shattered coursed through my arch once again but rested at my elbow, where the arm of the Doom Slayer was cut off. While the computer done it's thing I took another shot of dragon blood to give me a temporary boost.
Xingke and Gino looked on in horror -I assume- as my arm regenerated.
"What the hell is that thing?" Xingke asked pressing on his attacks while I dodged and weaved.
"T-this the symbol of revolution. Xingke. Remember it!" I fired energy beams at him. Xingke looked back at the Ikaruga for a second and then started flying towards it. He wouldn't risk gong inside it. So that leaves a few options but the most likely one being that the empress was on top of the Ikaruga.
I came to that conclusion due to the fact that she was standing on top of it.
I decided to hold Gino back.
"He's trying to steal your only bargaining chip. You're gonna let him?" Gino started flying circles around me.
"You think so?" I stated rhetorically. I'll admit I was curious to see what would happen. Lelouch couldn't have overlooked the fact that the Empress could escape. It was intentional, he wanted her to.
But why? Well let's find out. I grabbed onto the Tristan and with everything I had, threw it back at the Avalon.
I looked down at the ground, every Knightmare was firing at the Ikaruga, specifically where the Empress was, had it not been for Xingke moving in just at the nick of time she would've been Swiss... Human? Human Cheese? It's one of the two.
One of the Shen Hu's shield batteries had just given way.
"What are you planning Lelouch?" I thought out loud. An onslaught of missiles, artillery, bullets and bombs hit the Ikaruga, of the shields weren't disabled now then this thing was truly a beast, as the smoke cleared, a single frame stood in front of the Ikaruga.
The Shinkirō. The frame I had Rakshata finish development on. I figured Lelouch was the one piloting it. The main drawback of the Shinkirō was that in order to maximise the effectiveness of The Absolute Defense Field one must do the calculations themselves. It would take a genius, and someone with reflexes far beyond the ordinary.
Luckily Lelouch was Royalty and a genius.
He activated the Chest mounted Diffusion Structure Phase Transition Cannon. It fires a powerful beam into the prism, which in itself is is solid diamond, the prism refracts the blast into dozens of devastating pinpoint lasers. Kind of similar to how a Chaos Mine works. Although the Phase Transition was a lot cooler looking.
