Square Enix is bringing more fanservice to Kaku-San-Sei Million Arthur. The PlayStation Vita version had a crossover with Senran Kagura: Shinovi Versus and between November 16 and November 26 you’ll see girls from Infinite Stratos too.
How did the characters from Infinite Stratos get into Britain? Ichika Orimura wandered into this world and all of the girls hoping to date him followed. Now, Princess Guinevere tasked Arthur to organize dates with Ichika so everyone has a chance to spend time with him. Square Enix had a similar event for the smartphone version of Kaku-San-Sei Million Arthur and you can take a look at some of the special Infinite Stratos costumes here.
