Anyone know the name of this?

Ginger guy goes to this empty void world thing called the tutorial where he becomes a paladin or something holy like that who uses a mace.

luckily the first enemies are undead that are weak to both holy magic and blunt damage.

After beating that, he gets summoned to this undead forest where he meets some fire mage girl, he tells the fire mahe girl to burn down the forest which gave them both a ton of exp

There is this skill store thing where he improves his body

He returns to modern reality and then goes back into the place

He meets this spear weilding thief woman and gets to this door thing and I forgot what happened there

Later he went to an actual other world rather than a tutorial and killed a bunch of orcs, he then got his brain messed up because choosing the paladin class made him believe in some god person and bring holy words into his speech.
