The goddess of love pays a visit to Brunhild, calling herself Touya's older sister, Mochizuki Karen. Apparently she came there to refresh (enjoy a vacation) because Touya is so surrounded by love.
Our love affair goes around with 
the 1, 2, 3 beat of I, My, Me, Mine
I, My, Me, Mine,
unsere Liebschaft dreht sich mit 1, 2 und 3.
Nosso caso de amor dá a volta ao
som de 1, 2, 3, I, My, Me, Mine.
