Dareka, Zense ga Sugoude no Kidou Heiki Soujuusha de Aru Watashi ni Heion wo!

In a distant future, humanity has expanded into the far reaches of space, and the Pan-Cosmic Republic Space Force's Special Service Unit has become a dominant force in the cosmos. Kenji Tanaka, a skilled pilot with exceptional aptitude for operating humanoid Combat Suits, has been thrust into a leadership role, despite his initial intention to simply make a living. As a Senior Colonel, he is tasked with putting down planetary rebellions, a duty he views with disdain. His latest mission has just concluded when his ship is suddenly pulled into an emergent black hole. Instead of succumbing to the void, Kenji finds himself transported into a world of medieval fantasy, where he inhabits the body of El-All, the young heir to the Gluck family, a low-ranking noble in the realm. In this new world, the ruling nobles have mastered the art of piloting "Magicrystal Armors," advanced warframes that wield immense magical power. Kenji's experiences have taught him that entanglement with high command rarely ends well, and he must now navigate the treacherous landscape of this new world, where the line between honor and survival is constantly blurred.
