Isekai wa Smartphone to Tomo ni.

Mochizuki Touya is a perfectly ordinary young boy, but one day he is killed by God, who accidentally strikes him with lightning. But never mind, as an apology, God offers to bring him back to life, but in another universe, because on Earth, raising the dead is not done (or no longer done), and He will grant one of his wishes as compensation. After much thought, our hero asks if he can keep his cell phone in this new world. To face the future dangers awaiting him, God drastically increases his strength, agility, gives him insane magical power, the ability to use all elements, as well as to copy all existing "personal magic" just by having their name and description. Taking advantage of this, Touya decides to travel from country to country to help others and makes friends with many people...
