“OI! Heads up, Lancer!” Nagayoshi didn’t really give Cu too much of a warning before the tip of a spear nearly grazed, impaling the creature that had gotten a little too close to the other during combat. Considering the constant teetering sanity of most Berserkers, one might think that he might have nearly stabbed Cu with how close he was, but even in the throes of bloodlust, he was still careful not to murder or wound a comrade. Lifting up the beast high in the air, he grinned, all teeth as blood dripped down upon his form. “You really gotta pay attention, you know. Lucky I was here to look out for you, huh?” Was it really lucky when he was making a mess everywhere? Not that Cu would be bothered by that heavy iron scent that dripped upon Nagayoshi’s form and soaked the soil. Tossing the beast aside, he ran past Cu, ready to shove his spear into another enemy with just as much violence as the one he discarded.
It was difficult to not get excited and fall back on his old ways when a battlefield got heated. He couldn't let himself go and crush or behead anything that moved in his vicinity. He didn't want to scare or unsettle their dear Master. They already thought of him as a cool, reliable and laidback older brother-type of friend, so he couldn't ruin that image he has been working on ever since he was summoned. Meanwhile, Nagayoshi was having the time of their life, laughing, butchering and impaling everything and everyone that got in their way. Others most likely thought that battle-frenzy was a result of their servant class, but Cú Chulainn knew one didn't need to lose their sanity to go wild and have fun.
The Lancer used runes to make a wall of fire, buying time for the Master and the other servant to get away from this hellhole. "Don't worry about us, Master! I'll drag him by the hand so he doesn't get lost when we catch up!" He shouted at the mage, the usual carefree yet reassuring smile adorning his face when he waved goodbye. As soon as the Master was out of sight, Cú materialized his remnant of a past war. A second too late. Close, too close and fast to avoid impact. But that's what he gets for trying to keep up the charade in a battlefield.
Nagayoshi didn't even give him time to dodge before a blade struck dangerously close to his neck. But the one who was struck wasn't him, but the beast coming for his neck. When he turned around, Nagayoshi already was lifting and impaling their opponent, bathing them both in blood. "..." As expected, the Berserker didn't waste the opportunity to taunt him for his slip. But, rather than get annoyed and tell them they got it all wrong, he laughed and grinned wide. So this is how it was going to be, huh? Time to show the Berserker how the Red Branch fought.
Quick, the Lancer leaped forward and cut down the monsters running towards his friend, their bodies hitting the ground in two times. "Indeed! Lucky me you're so slow, I get to claim all their heads for myself!" The Master wasn't around anymore, so he didn't have to worry about anything besides winning anymore. "I gave you a head start. Now let's see if you can keep up with me, Oni Musashi!" It has been a while since he went all out.
