I was just so touched at the meaning of Ikuto's character transformation, Seven Seas Treasure! Nyaa....! For those who don't know, I'll tell it to you:

Seven:
Amu
Ran
Miki
Su
Dia
Yoru
Aruto Tsukiyomi (Ikuto's father)

Seas:
Aruto Tsukiyomi, Ikuto's father, was Lost overseas.

Treasure:
Amu Hinamori is the treasure Ikuto has been searching for.

anda would mostly get touched if anda were an Amuto peminat like me. But even if anda ship Tadamu atau other Amu/Ikuto related couples, anda could still get touched sejak Seven Seas Treasure's meaning.
