Kakeru Otouto

The Lonely Prodigal Son. Kakeru Otouto, born as the youngest son of a once-renowned samurai family, has always felt like an outcast in his own home. His older siblings, all accomplished and respected, have left him in their shadows, earning him the title 'Otouto' meaning 'the youngest' and 'lonely'. Striving to prove himself, Kakeru has dedicated his life to mastering the art of swordsmanship, hoping to one day make his family proud. However, his isolation has led him to develop a stoic and reserved personality, making it difficult for him to form connections with others.
