Ep 21. You Must Survive

The Galactic Empire continues their relentless attacks on Team Dai-Gurren's ground forces and the Arc-Gurren. Simon, struggling with the recent loss of his beloved Kamina, becomes increasingly reckless in battle, putting himself and others in danger. Meanwhile, Yoko and the rest of the team worry about the toll this is taking on Simon's mental state and fear for his safety.

As the battle intensifies, the troops become trapped in a massive underground cave system filled with deadly traps and obstacles. Simon, determined to prove himself and honor Kamina's memory, takes charge and leads the way through the treacherous tunnels. Along the way, he confronts his own fears and doubts, and must learn to rely on his companions to survive.

As the group fights their way through the underground maze, they discover a powerful new weapon that could turn the tables in their favor. However, the weapon comes with a steep price: using it would mean sacrificing the lives of several members of the team. Simon must make a difficult decision that will determine the fate of their battle against the Empire.

In the end, Team Dai-Gurren emerges victorious, but not without suffering losses and enduring great hardship. As they mourn their fallen comrades and draw new strength from their experiences, they vow to continue fighting for freedom and honor the memory of those who have sacrificed everything for their cause.
