Alkaloid no Hanayome

アルカロイドの花嫁

by Nijimi Oikawa

A story of a contract marriage between an immortal man and a lonely girl. Romelia, a lonely young woman, and Kutli, a high-ranked military officer, are solemnly married in the name of God. What they share, however, is not "conjugal love," but the burden of an "unbearable fate." (Source: Kodansha, translated)
