Vaniville Town, Kalos region. . .

Calem was already awake and checking something on his computer when he received an email from an anonymous person that read, "Day of Reckoning has come. Demons, Pokémon, and Angels now war with each other in Kalos. Due to unrestricted violence, human casualties have been incurred in various locations such as Lumiose City and Pokémon League. This email contains a device that will allow one to communicate with each of three warring factions: Law, Chaos, and Balance. It is called 'Demon Summoning Program' and it allows humans to enter conversation with demon, angel, and Pokémon. Demons and Angels have too much power to be contained in any Pokéballs, not even Master Ball made by Silph Corporation can hold them. That is why device shall be sent to any who receive this message: it initially can store six demons or angels, but will soon be upgraded to allow up to twelve. Device is called 'Arm Terminal' and contains a program that translates Demonic and Angelic languages into English. I hope that this is used."

Calem's eye were overwhelmed by an intense light, so he closed them for a few moments. When he opened them, there was a computer strapped to his right arm and it extended a cord up to a headphone on the boy's right ear. The computer was simple: it had a keyboard and a small monitor. Calem now knew that this was not a fluke, not some random dream in his head. The email and the item it contained were very real. Calem then checked his closet and found a sharp katana that not been there when he went to bed yesterday. Sheathing it, Calem left his room and said to his mother, "Today marks an important part of my life. My 'Journey' has begun and only when it is complete and I have found my 'Answer' that I will be able to return home."

"Good luck!" Calem's mother said as he left.

As Calem exited his home and walked towards the town exit, he was attacked by a Brutal Pixie and defeats it with a single swing of his katana. "Very interesting, young one." a voice said.

"Who's there?!" Calem said.

"Look behind you."

Calem turned around and saw Matador standing about four feet away from him. "Your journey has only begun. Which alignment will you choose for this Journey? Will it be Law? Will it be Chaos? Will it be Balance? I do not know, but at the least, accept this Pokémon." The demon pulled a Pokéball out of his Capote and gave it to Calem. The boy then sent out the Pokémon to see what it was. It was a Houndour. Matador then said, "I will await your decision in the next town. Become stronger, for the alignment you choose will decide the fate of the Pokémon World. No matter your choice, I will assist you."

Matador then left. Calem thought to himself, "This is going to be a tough Journey, but I must persevere and win because the fate of the world is at stake here." as he made his way towards Santalune Forest.

Info-dump: With the Shin Megami Tensei demons loose in the Pokémon World, there have been changes, specifically all Pokémon now have their moves categorized in different areas. The following shows what shall happen:

Offensively; Fire Type attacks are Fire element. Defensively; Fire Types are weak to Ice, unless otherwise specified with a Pokémon, resist Fire and Light, and take normal damage from everything else.

Offensively; Water and Ice Type attacks are Ice element. Defensively; Ice is weak to Fire while Water resists it, Water resists Ice and Ice absorbs it, Water is weak to Electric while Ice takes normal damage, Ice is weak to Physical while Water takes normal damage, Water and Ice take normal damage from Wind, and everything else deals normal damage.

Offensively; Electric Type attacks are Electric element. Defensively; Electric Types are weak to Wind, unless otherwise specified with a Pokémon, resist Electric, and take normal damage from everything else.

Offensively; Flying Type attacks are Wind element. Defensively; Flying Types are weak to Electric, unless otherwise specified with a Pokémon, resist Wind, and take normal damage from everything else.

Offensively; certain Psychic Type attacks and all Fairy Type attacks are Light element. All other Psychic Type attacks are Mind elemental status ailment skills. Defensively; both are weak to Dark and repel Light, Fairy Types resist Almighty while Psychic Types are affected the same way anything is hit by Almighty, Psychics void Mind while Fairies resist it, and take normal damage from everything else.

Offensively; certain Ghost and all Dark Type attacks are Dark element. All other Ghost Type attacks are Curse elemental status ailment skills. Defensively; both repel Dark, Ghost Types are weak to Light while Dark Types void it, Ghost resists Curse while Dark repels it*, Dark voids Mind while Ghost is affected normally, and take normal damage from everything else.

Offensively; Dragon Type attacks are Almighty element, which deals three times the normal amount of damage to everything that doesn't resist it. Defensively; Dragon Types are weak to Ice, Light, and Almighty**, resist Fire and Electric, and take normal damage from everything else.

* Many Curse attacks are also Dark elemental, explaining this repel nature. It also means that if Curse is voided or repelled, but not Dark; the target will still take damage from those attacks. However, if Dark is voided or repelled, but not Curse, only the status ailment will hit its target.

** Despite being listed as a weakness, Dragon Types do not take extra damage from Almighty attacks. They are merely knocked down by them.

Resist means that an attack will only deal half the expected amount of damage.

Void means that an attack will deal no damage whatsoever.

Repel means that the expected amount of damage dealt by an attack is sent back to the caster.

Absorb means that an attack will instead heal by the expected amount of damage.

Weak means that an attack will deal twice the expected amount of damage.

Ailments is a general term that applies to all Mind, Curse, and Nerve attacks. If a Pokémon, Demon, or Angel voids Ailments, that creature is completely immune to those moves.
