Namida Akashi is a young boy who becomes a member of the Crasher Squad, the elite Earth defense force featured in the anime. His parents were killed during an attack by the alien forces of Gishin, leaving him orphaned and without a home. With nowhere else to turn, Commander Otsuka allows him to join the squad, where the older members can look after him.

Namida deeply admires Takeru Myoujin, the main protagonist, and this admiration fuels his eagerness to prove himself as a capable member of the team. He is energetic and brings a sense of optimism to the group. Despite his youth, he is a skilled pilot of the Ra robot, which combines with other units to form the titular giant robot God Mars, specifically forming its left leg. During battles, he often takes on tactical roles, demonstrating sharp instincts and a willingness to contribute beyond just piloting.

Personality-wise, Namida is portrayed as quiet and introverted, yet he possesses a strong sense of empathy for others. He is the youngest of the squad and often serves as the emotional center of the team, showing compassion that helps strengthen the bond between the pilots. His initial motivation is driven by a desire for revenge against the Gishin for the loss of his family, but over time he grows into a confident and respected pilot who fights to protect his new found family and Earth. His development is marked by a shift from a vulnerable orphan seeking purpose to a steadfast member of the team who earns the trust of his comrades.
