In Another World With My Smartphone

After dying due to God's mistake, Touya is reborn in another world! There he meets the twin sisters Elze and Linze, and starts his new life in another world along with the smartphone he got God to let him use in the new world.

While surprised by the differences from his previous world, Touya is growing accustomed to living in the new world. Together, he, Elze, and Linze accept a mission to head to the Royal Capital. Along the way they encounter a young samurai, Yae.

Touya and the others journey to the ancient royal capital to defeat a dullahan. After finishing their quest, Touya and the others explore the underground ruins for treasure, but instead they find a magic beast made of crystal!

Touya is brought to the royal palace by the Duke. There he finds the King, bedridden, on the verge of death after having been poisoned!

Touya and the others set out to investigate some magic beasts, but it turns out their destination is the castle of a mage who researched slimes, which they'd all been avoiding (though Touya seems excited?)

After receiving a huge mansion in place of court rank, Touya and the others begin living their usual dense, thickheaded lifestyle. They receive a mission to go to Mismede, but on their journey they encounter a dragon attacking a village!
