Shakugan no Shana, Witch Craft Works Recommendations
Strong and weak are not hot issue anymore in anime. I mean those two are usually implemented in the kind of hero and anti-hero characters. But only few anime that involves the strong and weak as a pair of lover. One of them is Shakugan No Shana. It is really similar with Witch Craft Work in the term of character's background. Sakai Yuuji and Takamiya Honoka are defined as weak person who know nothing about fighting. Kagari Ayaka and Shana are professional that already have goodly skills to annihilate the enemies. Their element is also not different. Both is using fire as basic attack. So,
In Shakugan no Shana and Witch Craft Works, both main male prontagonist being protected by a main heroine, who also has fire power.. As the story progress, both male prontagonist also join battle together with main heroine, and develop romantic feelings..
If you're familiar/fan of the idea where a female lead saves a guy then become close together and works to achieve a certain goals. you should try these two awesome anime. very worthy of your time.
