In the English dub, Sai was given a British ethnicity, which seems
to fit his proper manners and social refinement. A true fish of
the sea, the bearer of the Torrent armor enjoys the finer things
in life. His father died early on in Sai's life and so he was raised
by his mother and sister(10 years his senior). Thus, he has a very
gentle nature. Sai's best friend is Kento.
Sai's family, the Mouri, is descended from Mouri Motonari, a famous
naval general in Southern Japan. During the Meiji period, the Mouri
family had dukehood. Sai's home is in Hagi in Yamaguchi (YST version).
For generations, the duty of the Mouri family is to protect the
Hagi Sea. Every member of the family is well acquainted with the
sea, Sai more than others.
When Sai was fifteen, he read the ancient documents of the family
and learned of Torrents' existence. Part of an old passage to manhood,
the males of the family would dive into the Hagi Sea near their
home. The sea is very deep, Sai can dive down to the bottom without
an air tank. It was at the bottom in a crevice that Sai foung Torrent.
He also had some help from his orca friend, Suiki. Sai told his
mother later and learned that she also knew about the armour. She
said, "At last it has come."
Sai's light blue armour is Torrent, Water, and draws power from
any water source. He has a tanto (dagger) behind his right shoulder
and wields Suiko Yari, actually a combination of a trident and mancatcher.
His special attack is Super Wave Smash, which is a large horizontal
pillar of water.
Having been raised by his mother and sister, Sai has a very gentle
and polite personality. He is considerate of others and doesn't
like fighting. He has trained in both the spear and bo since he
was young as part of his training to become the next head of the
Sai is starting high school at the beginning of the TV series. The
Japanese school year starts in April and Sai was born the month
before so he is one year ahead of everyone else. He lives in an
apartment in Tokyo for the entire Ronin storyline.
Sai first met his sister's fiancé when he went back to Hagi
to visit his mother who had fallen ill again. This was during that
interlude between Talpa's death and reappearance. Kento went with
him because he knew the area where Sai lived was famous for hagiyaki,
a type of pottery. Kento thought it was food.
At first, Sayoko was going to leave the family. If that happened,
Sai would have to give up high school and being a Ronin in order
to come back and take care of the family business. While trying
to get to know his future brother-in-law, Ryuusuke accidentally
insults Sai by asking him if he hates the sea. Sai is upset because
his sister is giving up her own dreams in this marriage and is even
further enraged by her fiancé's lack of knowledge of the
Sai puts his armour back where he found it and then challenges Ryuusuke
to a diving contest in the Hagi Sea, whoever dives deeper. Shizuka
is surprised when Sai dives in without a air tank. Before they've
finished though, Kento calls them back up. An oil tanker has spilled
oil over the Hagi Sea. Sai dives back down with Ryuusuke to get
his armour. However, the place he put it in has become covered with
rocks. As Sai tries to move the rocks, Ryuusuke sees a giant orca
move toward Sai. Shizuka throws himself in between them, fearing
for Sai's life.
This act totally changes Sai's opinion about Ryuusuke. Sai signals
that everything is alright to Ryuusuke. Ryuusuke watches in astonishment
as Sai hugs the orca. The orca opens its mouth, in which is Sai's
armour crystal. They ride Suiki to the surface and Sai calls his
armour. Using his power, he cleaned up the oil spill. Later, Ryuusuke
decides to marry into the Mouri family. Sai and Kento return to
Though Sai is gentle and congenial on the surface, when angered
he is probably the most dangerous of the Ronins. Sai is a quiet
focused anger which lasts longer and is more powerful than a loud
