This one is seriously lacking in information... like what were the voices summoning him and also how he knows what skills to use. He just randomly calls out a skill and it works. There is no status to list his skills or any knowledge necessary to activate magic. He just wants it, and it works. He is also too calm for a dude stranded in the middle of a nowhere forest with possible monsters and "black gas" like evil beings/miasma.
- Imagine if he yelled out "WORLD DESTRUCTION" and the world explodes on him. Or imagine him just yelling out "DEMENIONAL SHIFT" and then he suddenly appears back in Japan...
