Isekai wa Smartphone to Tomo ni.

Touya Mochizuki, 15, is unintentionally killed by God. In order to make amends, God permits his resurrection; however, since he is unable to bring him back to his previous existence, he is instead reincarnated into a fantastical realm along with any particular demands. Touya asked God to modify his request so that he may take his smartphone with him into the new realm. As a result, even though Touya cannot use it to communicate with his previous world, the phone can still work normally, access data from the old world, and use capabilities that are pertinent to his new world, including the GPS function to travel to areas that are fully identified on it. Touya's magical, mental, and physical powers are also substantially enhanced as an additional expression of God's regret for the inconvenience of having to kill him. Touya makes the most of his second chance at life by making friends with a wide variety of people, mostly women and influential figures in the new society. With his new allies, he sets off to visit several nations, resolving political conflicts and trivial objectives while casually having fun.
