Cyan is: Unable to focus on Porom's bad durability and speed, having to charge up all his damage. He also lacks any kind of protection against most of Porom's crippling statuses or powerful Holy spell. His heroic nature works against him, as he surely won't be as quick to strike down a small child as he would be to smite a villain or even a more heroically inclined adult. Much like her brother, Porom has a nasty variety of ways to win, and much like the poor scrubs who stood against Porom during her first ascent to glory, Cyan has no way to seriously harm or stop Porom before she cripples and defeats him. Losing to a little girl is a pretty sure sign you belong in light, but Cyan can hopefully pass this off as 'training' and not have his ego be too bruised after the fact.
