Tomonori Michitani, called Tomo, serves as the protagonist’s intellectually curious and idiosyncratically minded companion. Driven by a passion for astronomy, scientific inquiry, and voracious reading, he thrives in high-stakes scenarios by engineering unorthodox solutions rooted in academic rigor. His quiet, analytical nature positions him as the group’s strategic linchpin, deploying technical expertise and theoretical knowledge to outmaneuver threats while avoiding physical altercations. Though reserved in group interactions, his perceptive observations and methodical problem-solving prove indispensable during crises. Available records outline these traits exclusively, with no expansion on backstory or extended character development.
