Isekai wa smartphone to tomo ni. - Season 1 (2017)

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...No one knows how to treat it, and many believe there's no hope of saving him. Yet high-spec Touya handles the poison with ease. He saves the King with his super Healing magic, Recovery, and even catches the criminal who poisoned the King quickly, bringing everything to resolution. Meanwhile, after watching Touya's actions, Princess Yumina makes a startling declaration.

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!

Touya's party heads out for Mismede once more. When they finally arrive in Mismede's royal capital, Berge, they head to the palace for an 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. At Sushie's request they head back to Mismede where they find Leen and Paula. Leen asks Touya and the others to investigate some ancient ruins.

Touya arrives in Oedo, a Japanese-style castle town within Tokugawa Ieyahsu's domain. At Yae's home 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.

When Touya returns to the mansion, the problem of taking his brides awaits. Yumina and Linze push and push until Touya accepts his engagements. Even Elze and Yae get to join in the polygyny.
