Square Enix launched the Lord of Vermilion fantasy collectible card game in June 2008, and the game has since spawned the Lord of Vermilion II, Lord of Vermilion Re: 2, Lord of Vermilion III, and Lord of Vermilion IV sequels, as well as the Lord of Vermilion Arena Windows PC game.
The Lord of Vermilion III game previously inspired a six-minute special anime video.
The Lord of Vermilion IV game will update on June 28, and will include the characters Haruo Yaguchi and Akira Ōno from the upcoming Hi Score Girl anime.
In addition, Square Enix has multiple events planned to celebrate the game series’ 10th anniversary, with the anime series among them.
