Yuuki Yuuna is a Hero: Churutto!

A group of pure young girls gathers from various eras at the club room of the Hero Club in Sanshuu Middle School in Kagawa with a duty to protect the peace. One day, the club president, Fuu, told them that they will come together to make a special udon.

In order to set an example for everyone, the original Hero Club started making a trial udon. Since there are two members who are good at cooking, they were laughing at the easy idea that they would be able to complete the "Hero Club Udon" today, but then the.... incident happened.

The three Yuunas worked hard to make udon noodles. However, perhaps they put too much effort into it, and the dough turned out to be harder than expected. With their motto of "act quickly, don't think", the three Yuunas get out of the jam by using the only means available to them

Wakaba and Tamako were feeling like udon after entering the hot springs. What is Udon? While Wakaba is searching for the direction of Hero Club Udon, Tamako is doing the opposite. That is because there are tall mountains in front of her eyes!

A sleepover party for the younger group, consisting of elementary school students and junior high school students. The topic of discussion was how to make the best udon. They discuss various opinions such as what should be tasty, what should look good, etc., and finally complete the best udon ......?

In the Divine Era, when Shikoku became the world, udon is the staple food and the national dish. However, among the Heroes summoned from all over Japan in the past, there were definitely those who favored soba and ramen. There is no way that this will not cause conflict.
