ディオスクロイ・カストロからのお返し。

兄カストロはこの時期何もするつもりもなかったが、
妹が「お返しはせねばいけませんよ兄様」
と言うものだから渋々用意したモノ。

その輝き、
海上にゆらめく光たる「聖エルモの火」そのもの。

Valentine's return gift from Castor of the Dioscuri.

Castor hadn't planned on doing anything for this occasion, but he changed his position after his sister scolded him, insisting that he should give you something in return for your chocolate.

Its radiance is St. Elmo's fire, so often seen flickering above the seas.
