Seed- Voiced by Nobuhiko Okamoto, Seed is closed off from those around him and seems to have trouble working up the motivation for doing the things he should be. Regardless of this, he has a strong sense of justice and is very kind. When in very quiet surroundings, his ears are good enough to hear the heartbeats of others. Aqua- Voiced by Yu Sarizawa, Aqua is Seed's younger sister-in-law. A bit of a worrywart, she is every mindful of her brother. Known to lack self-confidence and for being a bit shy, she still seems quiet childish for a girl of her age.
