In Another World with My Smartphone

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.

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!

Before him lies a young girl in white panties. After Touya arrives at the aerial garden, he's greeted by a young girl in white panties, Francesca. She's the keeper of the garden.

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?!
