Teppachi! Iron Bowl Steel Helmet

During high school, a player who was the star of the rugby club and attracted national attention got injured due to overconfidence and excessive play. After being blamed by his teammates, he retired in isolation. After graduation, he lived alone without finding a stable job, leading a carefree and idle life. One day, after an argument that attracted police attention, he got fired from his construction job, and his apartment was also asking him to move out due to unpaid rent, leaving him in a desperate situation. In such circumstances, a man said to him, 'I have a job that suits you!' 'The dormitory is well-equipped, with three meals a day! It's perfect for someone proud of their physical strength like you!' The job introduced... was actually! The 'Ground Self-Defense Force', protecting the peace and security of the country! 'Kuniaki Nao! A man born for the country, with a heart as broad as the universe! Wasn't he meant to become a self-defense officer!' Initially, Nao rejected the man's recommendation, but he thought, 'Without a job, I can’t find an apartment, and I can’t live like this. If trainees get paid, then I’ll agree for now.' With half-hearted determination, he became a candidate for the Ground Self-Defense Force. What awaited him in this half-hearted state was harsh training. The day he encountered the 'Ground Self-Defense Force' became a turning point, as he met significant companions, fostered friendships, and experienced moments of love, gradually realizing the importance of connections between people and growing bit by bit. The young man who joined with a mindset of 'self-destruction' transformed from that immature life into a true 'Teppachi' life when he became a genuine self-defense officer worthy of wearing the protection cap.
