Noblesse Season 1 Episode 5 A Friend's Hand / Fight for...

After the intense battle with Regis, M-21 is taken in by Frankenstein and Rai. When he wakes up, he finds out that he is no longer a human but a modified human with enhanced abilities. Unable to accept this reality, he confronts Frankenstein and Rai, demanding to be returned to his normal human state. However, they explain to him that there is no going back and if he wants to survive in this world, he has to embrace his new powers.

Meanwhile, Regis is still recovering from his injuries but decides to visit his friend Seira who he hasn't seen in a very long time. He is surprised to find out that Seira has become a completely different person - strong and independent. They catch up on old times and talk about their experiences as Nobles.

Just as they are reminiscing, they receive a call from Frankenstein who requests their help in rescuing a group of humans who have been kidnapped by a dangerous organization. Regis and Seira immediately agree to help and set out on a mission with Frankenstein, Rai, M-21 and Tao.

The team arrives at the location only to find out that they are heavily outnumbered. In the midst of the chaos, they discover that some of the kidnapped humans are actually modified humans like M-21. This infuriates M-21 and he charges ahead, determined to rescue his fellow modified humans.

The battle intensifies as the team fights against powerful enemies. Regis and Seira use their unique abilities to take down multiple opponents at once while Tao and Frankenstein are busy hacking into the enemy's computer systems. But the most impressive display of strength is from M-21 who single-handedly takes on a large group of heavily armed soldiers.

Despite their efforts, things start to go downhill when a powerful enemy named Crombel shows up. He is the head of the organization and has been experimenting on humans and modified humans for years. Crombel reveals that both M-21 and another modified human are part of his latest experiment to create the perfect being.

As the situation seems impossible, Rai finally enters the battle. With his immense power, he proves to be a formidable opponent and takes on Crombel head-on. The team takes advantage of this and starts to rescue the kidnapped humans.

In the end, they manage to save all of them and even bring back some of the modified humans to their base. But even though the mission was a success, M-21 is still struggling with his identity and his place in the world. The episode ends with him contemplating his future and wondering if he made the right choice by joining the Nobles.
