Arpeggio El Lelena is the older stepsister of Lelei La Lelena, who is, like her, a student of Mimoza at the Magic Academy in Rondel. She mainly focuses on alchemy and more specifically the study of minerals. This field is quite expensive in her world and receives little funding, causing her to live a life of poverty. In order to make extra money, she copies books by hand as the printing press has not been invented in the Special Region. She is extremely jealous of her sister's exploits, has a very short temper and has even fought with her sister in a series of magic battles thirteen times. Neither one ever has intention to do serious harm to the other, though their last fight resulted in severe property damage. Deep down, Arpeggio has great affection for Lelei, going as far as knitting new clothes for her. Her competitive and jealousy for Lelei is so big enough that she willing to do anything to beat her sister even trying to marry Itami due to his noble status.
GATE
In August of 20XX, a portal to a parallel world, known as the "Gate," suddenly appeared in Ginza, Tokyo. Monsters and troops poured out of the portal, turning the shopping district into a bloody inferno. The Japan Ground-Self Defence Force immediately took action and pushed the fantasy creatures back to the "Gate." To facilitate negotiations and prepare for future fights, the JGSDF dispatched the Third Reconnaissance Team to the "Special Region" at the other side of the Gate. Youji Itami, a JSDF officer as well as a 33-year-old otaku, was appointed as the leader of the Team. Amid attacks from enemy troops the team visited a variety of places and learnt a lot about the local culture and geography. Thanks to their efforts in humanitarian relief, although with some difficulties they were gradually able to reach out to the locals. They even had a cute elf, a sorceress and a demigoddess in their circle of new friends. On the other hand, the major powers outside the Gate such as the United States, China, and Russia were extremely interested in the abundant resources available in the Special Region. They began to exert diplomatic pressure over Japan. A suddenly appearing portal to an unknown world—to the major powers it may be no more than a mere asset for toppling the international order. But to our protagonists it is an invaluable opportunity to broaden knowledge, friendship, and ultimately their perspective towards the world.
