Senchi Kara Kaette kita Takashi-kun. Futsuu ni Koukou Seikatsu wo Okuritai

With the devastating extraterrestrial invasion war finally drawing to a close, hero Shibusaki Takashi officially retires from military service and makes his long-awaited return to Japan. Having survived countless harrowing days on the absolute brink of death, all he desires is the ordinary high school experience he spent years dreaming about. Filled with eager anticipation, Takashi steps into his new life hoping for nothing more than peace, quiet, and the simple joys of youth. However, reality quickly shatters his expectations. Instead of a peaceful routine, his daily life is turned completely upside down by a vibrant group of unique and beautiful girls. Among them is Natalie, a former comrade-in-arms from his brutal campaigns in Northern Europe. Surrounded by these extraordinary individuals, Takashi finds himself dragged into unexpected battles day after day, leaving his cherished dream of normalcy in ruins. As chaos continually erupts around him, he is forced to confront an unsettling question: has his life lost its sense of normalcy because the world remains dangerous, or has the battlefield fundamentally changed who he is?
