DARWIN'S GAME and AIR GEAR

DARWIN'S GAME (2020) and AIR GEAR (2011)

couldn't help but notice a bit of similarities

Both series is about a secret tournament held and in certain locations and only those connected to the founders or those who were invited can enter the tournament. Both have watchers or overseers that reports the result of the match between individuals or clans. Clans from both series have their own territories and leaves their marks in order for their opponents to know who rules certain territories. Winners depending on the agreement and the wager can win everything from the loosing team including the looser's territory.

For the characters:

Kaname Sudou the main male character from Darwin's Game

and

Itsuki "Ikki" Minami the main male character from Air Gear

both almost similar not because of their personalities but their character development although Kaname was a bit late in the game before he completely got used in the game. Ikki on the other hand was more aggressive.

they are similar because they were both guided by a veteran player and the main female character of the series. Shuka for Darwin's Game and Ringo for Air Gear. Both also carries an alias Queen of Thorns and both fashions twin tails except Ringo is a lot more bustier than Shuka.

both girls were key characters for the development of the main male characters of the series.

Both characters also chose the bird crow or raven a black bird.

Sunset Ravens chosen by Kaname

Kogarasu Maru or translated into English as Little Crows chosen by Ikki

Too bad Darwin's Game only had 11 episodes, they could have pushed for more but I guess they might be planning on making a second season for the series.

Might as well wait and see if there will be a second season for the Darwin's Game which was quite hinted in the last episode of the series. With that Air Gear is another that also made me feel that it needed a second season and not an OVA, but it is still something to wait and see since a long interval for a sequel or a new season for an anime series is quite common in anime.
