Hina Logic - From Luck and Logic

The world is at peace once more after a year since the demon gods invaded the city of Naien. Princess Liones Yelistratova, from a small nation, begins her studies at a school that is a special facility sponsored by ALCA that educates logicalists to preserve world peace. In Class 1-S, Liones is surrounded by several interesting classmates, including Yayoi Tachibana, the class's elegant spokesperson, Mahiro Kyobashi, a tech-savvy student who enjoys looking for foreigners, and Nina Alexandrovna, a mature but reclusive student who takes pride in being a logicalist.
