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 with his smartphone. Together, he, Elze, and Linze accept a mission to head to the Royal Capital.

Touya and the others head to ruins on a new quest from the Guild to defeat a dullahan. There they encounter the ancient royal capital, abandoned after the capital was moved a millennium ago.

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

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. Then they receive a mission to head all the way to Mismede because she'd like to use Touya's Gate spell for talks with The Kingdom of Mismede.

Touya's party heads out for Mismede once more. Then they finally arrive in Mismede's royal capital, Berge. Their party heads to the palace and gains audience with King Jamukha. Then somehow Touya and the King end up doing battle in their fighting arena?!

After returning from the Kingdom of Mismede, Touya and the others enjoy their daily life. Yet behind the scenes the women battle over the bicycle Touya created! At Sushie's request they head to Mismede and return to find Leen and Paula.

Touya arrives in Oedo, a Japanese-style castle town within Tokugawa Ieyahsu's domain, and quickly heads to Yae's home. There he meets their servant, Ayane, and Yae's mother, Nanae, before hearing that Yae's father and brother went off to war with Ieyahsu.

After arriving at the beach where the Nilya Ruins lie, Touya and the others take a moment to enjoy the seaside. With so many beautiful girls in swimsuits, Touya's heart is racing!

When Touya returns to the mansion, the problem of taking his brides awaits. Yumina and Linze (mostly Yumina) push and push until Touya accepts his engagements. Even Elze and Yae get to join in the polygyny! Hey, are you okay with this, protagonist?!
