User Recommendations for 11eyes

In 11 eyes, a group of students are sucked into a different dimension of the world where time is stopped. Similarly, in Shakugan no Shana, Flame haze can put up a fujutsu (stops time also) which encompasses a specific area and also turns everything red too. The male protagonists of both series (Kakeru from 11 eyes and Yuji from SnS) are fighting to protect their loved ones (although Shana is more like the protecting one in SnS).

Both have dense main characters who are special in some way. The characters fight in another world and are chased by some eeeevil organisation. Both are love triangles with a red head which uses swords and an annoying useless brown haired girl. Both try to be serious but fail miserably.
