Battle for the Sea

"It really is incredible…" Stella muttered. 

There was a hint of awe in her voice as she looked down at the palm of her hand. Much like the Sluice Form that Rune and Rienn had developed in the midst of their battle with the Seiya's Dragon Turtles, parts of her body were now made of a similar crystal blue liquid. 

She was connected to them both, even now–her half of the origin working as a catalyst for their fusion, and she could feel every change they underwent. This meant that she could use their Sluice Form herself, and she did so without hesitation. Though still unpolished, it was a powerful technique that more or less negated any kind of physical damage to one's body.
