Having received from his informants about the appearance of an outstanding first-grader at the academy, Eichi decides to attend a live of the newcomers in order to find this pearl and, if he likes it, appropriate it for himself.

…

Eichi is sitting in the front row of the concert hall, his arms crossed, as he skeptically evaluates the performances of young bands and singles, none of which he has liked so far. Tori is sitting next to him, having asked to go with him, and is trying to imitate his serious appearance.

The live is nearing its end, and no pearls have been found. The last idol enters the stage, and Eichi does not place much hope on them.
