Shadowverse Flame

Shadowverse Frame is a sequel to the anime version of Shadowframe. But you aren't required to watch Shadowverse to understand it.
It follows an MC Light Tenryu who enters a collage which teaches kids how to play the card game the show is based on. Unlike any normal person, he entered there without any knowledge of the game or anything. Just because he was told by some random stranger.

Basically the plot is about Light learning to play the game and gather members for the Shadowverse club he is part off which is missing members to become an official club.
The plot itself sounds rather stupid but ... it is entertaining to watch. The characters have strong personality except the MC and probably the only ones that carry the show.
The card game unlike in the predecessor gets properly explained and it is much more understandable. But some duels are a bit too fast paced and certain elements aren't as well explained as in Yugioh (at least in the Japanese version where they state the obvious in Arc V).

However, it is not well explained if the card game can actually hurt the players since the monsters seem to be solid vision and sometimes characters fly around after being hit by an attack, which makes it awkward why kids are allowed to play these kinds of games if it poses actual harm. And if they don't, why are they acting the way they do?
The former question can only be answered by watching the previous show. Regarding that, old protagonists appear and battle the new cast members. For people who had enjoyed the previous anime and liked some of the characters, they can see how they grew up to highschoolers and how "strong" they have become.

The new cast has some stuff too offer too. An older brother who has self-esteem issues because he can't live up to his younger brothers legacy. Someone who is very selfish and uses his skills to humiliate weaker players. Another one being traumatized by how her former senpai she looked up too got thrashed in a card game. A girl who tries to move out of her shell and tries to be herself being caught in the mids of stereo types.
They aren't handled as well it could be but for a kids show it does a decent job. My favorite character being Ren Kazamatsuri but the others are very enjoyable too.
The exception is Light who is basically a white piece of toast. The previous Shadowverse had a not very likable protagonist who is a gary stu, but that character had a personality. But Light is one of the most bland characters I have seen. He went to a college by a stranger and is insanely awkward playing things straight. He acts like a robot sometimes and not like how a human normally acts.

Despite these issues it is a really fun show to watch.
