| Takumi Iruma is accidentally caught in a summoning spell that takes him to the world of Mildgard. The Goddess Nolyn explains the spell was cast by the Holy Empire of Sidonia to summon three heroes.

He encounters a young girl named Molly and rescues her from a monster. In Sidonia the three heroes meet Empress Elizabeth. Hero Akane receives a Blessing of Revelation from Nolyn that tells her Elizabeth cannot be trusted. Molly’s parents Banga and Martha explain their village is a haven for craftsmen. Takumi chooses to be an Alchemist and a Blacksmith. Whilst searching for potion ingredients he encounters an Armoured Boar and a Poison Spider. Surprisingly the spider helps him, allowing him time to deconstruct the boar’s brain with alchemy, killing it. After healing the spider, he tames it into a pet, giving it the ability to speak to him telepathically, so he names her Maple, causing her to evolve into a Killer Spider. One of Nolyn’s Goddess friends is curious what plans she has for Takumi, given that when she sent him to Mildgard she also sent him a year into the past, long before the Empire summons the other heroes. ||||||

He then sells his potions to Papek for 7000 silver (¥7,000,000) and rents a house and workshop. Takumi notices the city has an inefficient sewage system, so he crafts a toilet that purifies waste. Papek is astounded at such an invention and places an order for 100 toilets. He also warns Takumi if word of his Light Magic reaches the Sidonia Empire, there is a possibility he will be kidnapped by the Sidonian Church of Holy Light, which believes all Light Magic belongs to them. To assist with production, Papek recommends buying a slave. Takumi is repulsed by slavery but soon realizes he will need the help as he must complete a quest once a month to remain an adventurer.
