Laila April

Laila is the older sister of Rikuto April. She uses a Pentan deck, but isn't a skilled card battler. When she and Rikuto were attacked by the Galaxy Triumviate, she called for a substitute card battler. However, she ended up battling against one of the members, and lost easily. Thus, Rikuto's space compass was stolen. After Rei returned the compass to them, Laila and Rikuto decided to join his crew. When they entered the Number One Starship, Laila was horrified by how messy it was. She quickly worked to get it clean. (Source: Battle Sprits Wiki)
