《Kaiju No. 8》 Full Analysis of the Brother Relationship Between Shoshiro Hoshina: The Shadow of a Genius Older Brother and the Path to Self-Affirmation
In the popular manga "Kaiju No. 8," the 3rd Division Vice Captain Soshiro Hoshina has gained countless fans with his superb swordsmanship and unique personal charm. However, beneath his seemingly easygoing exterior lies a past related to the "Hoshina Brothers" filled with competition and pressure. This experience not only shaped his current personality and fighting style but is also key to understanding the depth of his character. This article will delve deeply into the complex relationship between Soshiro Hoshina and his genius older brother.

The Giant Shadow of the Genius Older Brother - Sōichirō Hoshina
Soshiro Hoshina comes from a prestigious monster-slaying family that has continued since the Muromachi period. In this family that prides itself on the sword, his older brother Sōichirō Hoshina is a true genius. Sōichirō could quickly master any swordsmanship technique he learned, and his talent was so high that his younger brother Soshiro always lived in his halo and shadow.
From childhood, no matter how hard Soshiro tried, he could hardly reach his brother's level, which became a source of deep-seated inferiority and pressure within him. This power gap between the brothers was an important factor driving Soshiro's life choices later on.

The Fateful Duel and the Path of Divergence
The relationship between the Hoshina brothers reached a turning point in a duel that decided the family succession rights. In this duel, Soshiro was once again defeated by his older brother Sōichirō. After the defeat, the words his brother spoke to him completely changed the course of his life. Sōichirō believed that with the gigantification of monsters and the spread of firearms, the era of relying solely on swordsmanship was over, and he advised Soshiro to abandon the family's traditional path.
Although these words were harsh, they also awakened Soshiro. He chose to leave his family and join the Japan Defense Force, where firearms were the mainstream combat method, attempting to find his own path. This also explains why, within the Defense Force, he became one of the few elites who insisted on using swordsmanship.

Stepping Out of the Shadow: The Path of Self-Proving the Value of the Sword
Although his brother denied the future of the sword, Soshiro did not completely give up. He改良 the family-inherited "Hoshina-ryū Tōbatsujutsu," specializing in dealing with medium and small monsters that firearms found difficult to handle, finding his own unique position within the Defense Force. His ability when dealing with small and medium monsters even surpassed that of Captain Mina Ashiro, who excelled at artillery attacks.
Soshiro's efforts were ultimately rewarded:
- Recognizing Talent: With his keen observational skills, he pushed aside opposition to bring the immensely potential Kafka Hibino into the squad, demonstrating his talent as a judge of character.
- Obtaining the Identified Kaiju Weapon "No. 10": After a fierce battle with Kaiju No. 10, he not only defeated his opponent but also made him submit willingly, voluntarily becoming his exclusive weapon. This sword, tailor-made for him, is not only proof of his strength but also symbolizes that the path of swordsmanship he long insisted on has finally received the highest recognition.
In summary, the relationship of the "Hoshina Brothers" is an inspiring story revolving around the pressure brought by a genius older brother, the constraints of family tradition, and how the younger brother stepped out of the shadow to prove himself. Soshiro's experience did not stem from hatred between brothers but rather a complex mix of competition and respect. He ultimately, through his own efforts and indomitable will, carved out his own legend on an unpromising path, becoming the irreplaceable "Master of the Sword" within the Defense Force.
