Colonel Satoka Sono, become a spirit of the guardian shrine!

July 13th, Year 20 of Shuubun, the final stages of the Amur War. Harbin City, Heilongjiang Province, Chinese Dynasty. Here, a single maiden soldier was about to end her life. Torn limbs, a shattered beautiful face. Because she had been beautiful in days past, her current appearance was all the more tragic... Her name was Sonozarika, Senior Colonel. A volunteer soldier belonging to the 4th Division of the Human Liberation Front, and a loyal warrior who threw herself in front of an enemy soldier's suicide bombing to save her commanding officer. The division commander whose life she saved by throwing herself in front of danger, the adjutant weeping at the pitiful state of her superior officer. And the medical corps members working desperately to sustain the life of their wounded loyal soldier. Watched over by fellow soldiers who shared her cause, Sonozarika passed away. The soul of the maiden soldier who fought to save humanity's future now becomes a glorious spirit... (This is a prequel to the "Sakai Prefecture Maiden War Chronicles ~Special Mission Mobile Swordsman Chisato~" series. It is set more than 50 years before the main story.)
