Tohru Yanagi, a retired VR gamer who is not good at socializing, was so absorbed in the latest VR game that he lost his life due to carelessness playing "Last Fantasy" for 100 hours straight, his heart gave out and he died. However, his death only began a new life for him. He is reincarnated in another world, Clenaclem, a land of swords and sorcery and all of those typical isekai tropes. Tohru accepts, and naturally is sent to another world, under the condition that he will be given "the power of the game" by the god of games, Celuenon. However, Toru agreed to be transferred to another world, Clenaclem is a harsh world infested with the vicious monster, on the words of the unreliable god of games, Celuenon, who said, "I will give you the power of your favorite game," but... "A game is a game, but isn't it a card game?" "No, no one said the power of VR games."

I just said my favorite game. Well, I didn't dare correct it. With the "*ability to manipulate the power of cards*" given to survive in such a different world, and the Holy Spirit Waff, he set out on a journey to an unknown land. Without knowing the intentions of the gods who summoned Toru to another world.

### Abilities

In lieu of giving him any skills from Last Fantasy, Tohru instead was gifted a deck from "*Monster and Magic Masters*" - a physical card game he used to play in the past. And just like the trading card game, as long as he has the required mana he can summon any card from his deck, ranging from monsters to his faithful wolf-girl assistant Waff.

* A binder or deck case that collects the cards. It will appear also float in front of the user and disappear into the void and it has the appearance of a card binder with a similar metal cover. The page was not a card file, but a papyrus-like paper page. A deck/binder is a collection of cards that the user need to play a card game. A deck recipe system is like a list of cards built into the deck.
* It can have any number of decks as long as they are 50 cards or more. Some of them even made decks with over 100 cards. You can draw 6 cards from the deck at the beginning and draw 1 card each turn. Also, since it is a turn system, there is a first attack and a second attack, but the rule was that the player who started first could not draw on the first turn. This is a measure to reduce the advantage of the first attacking side.
* Only 4 copies of the same card can be included in the deck, and only 1 LR card with the highest rarity can exist on the field. If you wanted to summon the same card as the LR summoned by your opponent, you had to somehow eliminate the opponent's LR card.
* 20 hit points. In MMM, it was called Life Barrier. It seems that the player is a magician, and it is a barrier that the magician automatically wraps around. The main purpose is to use monsters and magic to attack each other and cut down the opponent's life barrier. and It was a defeat when this life barrier became 0 or when cards could not be drawn from the deck.
* To use a card, you must consume magic power equal to the card's cost. In order to obtain the magical power necessary for summoning and using magic cards, you must use the main magical power, which automatically increases by 1 every turn, or the magical power created using magical power generation cards such as land cards. did not become.
* There is an upper limit to the number of cards that can be used in a deck, which is 10 or 1/8th of the total number of cards in the deck. A 100-card deck is rounded down to 12 cards.
* Also, there are six colors of magical power: red fire, blue water, green ground, yellow wind, white light, and black darkness, and each can only be used on cards that correspond to that color. However, only the main magic power was called universal magic power, and it could be treated as a thing with all colors.
* It can store up to 20 of the user main body magic power, but the flowing magic power - that is, the colored magic power disappears at the end of the turn. MMM cards have something called rarity that expresses their rarity. Starting with the common that is included in the pack the most, the rank of rarity increases in the order of uncommon, rare, super rare, and legendary rare. It was often acronymed C, UC, R, SR, LR.

Tohru Yanagi is a vivid gamer in some point he is addicted to a card game called "*Monster and Magic Masters*", commonly known as MMM, which I was addicted to before he was completely addicted to VR games. Tohru remembers that this mark was always drawn on card packs. Tohru learned and gained to how his ability work for survival, giving him a advantage and good strategy used not for one-on-one combat situations, but for battles where many are mobilized and leading his troops/Units to victory in many battles while alive.

In addition to the *ability to manipulate cards (TCG)*, *language ability*, and *mental toughness (Mind Eye)*. The rest is a robust body that *nullifies poison* and *disease*. The scale of the Tohru survival by Life (*Reduce Life Barrier*) percent 20/20 as an act of barrier and given Universal Magic (*Universal Magic Power*) 20/20 as mana.
