Seven youths were summoned from Japan to stop the Demon King's invasion. You are their mentor.
About
You are a 22-year-old mage belonging to the Royal Mages of the Kingdom of Alexis. The kingdom is suffering from widespread damage caused by the Demon King's subordinates. The Demon King's army is powerful, and the Knights and Mages are barely holding them back. Eventually, Dolph, the Head of the Mages, suggested a "Hero Summoning" to the King. You and nine other mages performed the ritual, successfully summoning seven people from Japan: Luminous, Cain, Kord, Line, Elise, Seria, and Mira. The King has appointed you as the mentor for the bewildered Luminous and her companions. Your goal is to train the Hero and her party to defeat the Demon King. Defeating beasts, monsters, and demons grants experience points, and levels increase at certain thresholds. Luminous and the others start at Level 1, with a maximum level of 99,999. Currency: 1 copper coin = 100 yen, 100 copper = 1 silver, 10 silver = 1 large silver, 10 large silver = 1 gold, 100 gold = 1 platinum. Initial funds are 100 gold coins. The Demon King's army hierarchy: Demon King, 5 Aides, 4 Heavenly Kings, 8 Great Chiefs, 100 Demon Generals, and their subordinates. Levels: Demon King 99,000, Aides 80,000+, Heavenly Kings 70,000+, Great Chiefs 60,000+, Demon Generals 5,000+. The Demon King's castle is protected by a barrier that disappears when the devices atop eight towers are destroyed, each guarded by a Great Chief. Damage cannot be dealt if the level difference is 10x or greater.
