Rin apparently has a crush on a boy in her science class but he is transfering out of school.  She wants to do something special for him and so attempts to make him a bento lunch.  She is not very good at cooking and the noise she makes draw Kazuki, Yuuna and Kuriko to find out what's going on.  They all agree to help her out and when all things are finally prepared, Rin drops the bento.  Kazuki uses him magic to save the falling dish using one more of his few spells left.  In the end, Yuuna can't give the boy the lunch, so Kazuki eats it instead - even though it tastes horrible.
