Amelia Blanchette Falls Over and Over Again (v1.0.2) by AVANTGARDE

Their mission is to confirm rumors of demon summoning at the academy. Masamune thinks it will be an easy job dealing with students, but his superior suddenly delivers a shocking statement.
"If you fail this mission, the Magic Corps will be disbanded."
The Magic Corps is disliked by the higher-ups in the kingdom's army. It was only natural that they would be kicked out if they couldn't produce results.
Amelie is determined to succeed at all costs, in order to improve the status of magicians. On the other hand, Masamune still remains optimistic, thinking about something else.
"A mission alone together... I'll confess to Amelie here."
Since they spent time together since childhood and she taught him magic, Masamune has had feelings for Amelie.
However, the Caledony Magic Academy is fraught with various hidden agendas. Masamune is not the only one attracted to the charming Amelie Blanchet.
In the unexpected struggle of the mission, Amelie is seen with another man.
Before the failed Masamune, a mysterious girl appears.
A week that loops through magic.
Where will the story lead us...
