Sei Moesu no Hakobune

Humanity has formed the "Earth Federation," achieving what seemed to be lasting peace and prosperity. However, this stability is disrupted by a sudden barrage of comets. Fifty years later, a girl named Moena is concerned about her academic abilities and chances of attending a top high school. Unexpectedly, she receives an invitation to the elite Institute of St. Moesu, without undergoing any exams or interviews. The circumstances behind her acceptance remain unclear, as does any connection to the earlier comet event.
