Lignum Vitae is an experienced Burst Linker, having been on the Great Wall commanding team for at least 3 years.
Lignum Vitae is the name of what was considered the hardest wood, and she inherits its hardness, being a highly defensive Duel Avatar. Her armor looks like an evening dress.
- Unnamed parasol – A wooden parasol. It has a sharp hook for a handle and can extend and retract quickly.
- Calvin Cycle – A special move that transforms Lignum Vitae into a tree 3 meters tall with a 30-centimeter-thick trunk, with her parasol forming the top half. In this mode, Lignum Vitae is immobile and highly defensive, capable of surviving many physical attacks unscathed. She then starts producing a glowing fluid that can fill up her allies' SP gauges.
- Krebs Cycle – A special move that transforms Lignum Vitae from her tree mode back to her humanoid mode.
