Dark achieved his dream of obtaining a version of blue-eyes white dragon thanks to Pandora senpai although Dark is scared to tell her the truth about the materials he used since he does not know how she reaction

In his second year, Dark is allowed to obtain another monster as demidevimon and he managed to obtain Agumon and his evolutions through the card pride are related to the digimon route of Agumon from Digimon Squad

The reason why I grouped Dark and white's stag is because the stag saved dark when Lady devimon was corrupted by a mad moon goddess and helped save the life of dark as demidevimon who was in lady devimon at that time.

Just imagine the potential of the stag if dark used his sins cards in the maybe dark would get a version of the pokemon Xerneas when the deer evolved

Reason why white despises and cannot use the potential of the stag.

He hardly ever uses it in his duels

When he drew it, he decided to give up, considering it a useless card, when he faced Diana

First official duel between dark and white

[Mind Light], which can express the power of the soul, once helped him awaken the [Evil Beast] that was corroded by the Moon Goddess.

The upper limit of this nirvana depends on the magister's mental strength, which is a typical psychic ability that will be amplified by the magister's thought and emotions.

As the son of a brave man, if Whitte can make good use of this [soul light] and put his courage into it, he should be able to get good results.

It's a shame that the [Light of Mind] without the magister's spiritual augmentation is just normal nirvana unleashed by magical one-star elves.

This shows that white does not know how to use stag to its full potential.

The slow development of the plot happened from the things that were already noticed in the spoilers since it took more than 400 chapters for Dark to finish his first year so the pace is super slow and considering that it has more than 600 chapters and in novelupdate just goes to chapter 62 obviously have a lot of road and need stamina and patience to be able to enjoy this story

What Dark does during his spare time as mentioned in previous spilers where for the most part, he will watch the MC as a spectator for most of the main plot, but he won't avoid getting into the mix of things if he has to, which he usually is. Near the end of the arc when something important to his future development occurs and aside from that, he spends most of his time experimenting and playing cards which makes most of the events seem repetitive until the duel or fight scenario of life or death.

What you have already been warned about if you read the spoiler even the same synopsis and the protagonist tells you that the game where he reincarnated used the elements of other franchises

About your comment about Dark, do you not remember that he was an adult who woke up in the body of a 12-year-old boy with almost no important information about the game and you seriously hope that in a world where mathematics is at a lower level than his previous world are able to make a problem for Dark or that some children can compare themselves with respect to intelligence on that subject and you mean the age that enters the first years was 12 years old and it is true that compared to how the characters of little tyrant these look very immature in comparison just take that as a story for fun

(And by the way if there are noble people who are manipulative or think like noble but they are teenagers or adults but most of them cannot harm Dark due to the protection of his mother or dark plot armor)

At points that I agree with you is that the narrative form sometimes becomes very repetitive at certain points and continues to praise things such as the virtues of effort, dedication, and other virtues to explain the victory of some people or the constant advance of dark

About harem I already said it, the girls are the ones who fall in love with him but not dark with them since he is busy with his own affairs and it will be difficult for him to be in a relationship since so much dark before and after obtaining his memories he does not have no experience in a real relationship

I also agree with White and his affection card but he really during the course of the story he does not use it due to the scolding he received from the teacher and due to his own morals so there is not much problem in that.

Your comment about Emma I don't remember if I saw Harry Potter so I'll keep quiet but it is obvious that she is one of the author's favorite characters because she has a longer screen time although she is not related to Dark as a friend.

Although I hope that she gave more screen time to girls more interesting in second year since Emm if I'm honest I am not interested in she as a rival or love interest
