Items

 * The Holy Sword Terra di Madre of Mother Earth - a powerful holy sword that she received from the king at the beginning and it has the power to control Earth Element. Its main attack allows spikes to form from the floor and attack enemies.
 * The Holy Sword Altura of Mother Ocean - a powerful holy sword that she received from the king at the beginning and it has the power to control Water Element. It’s main attack is traveling along the ground to deal water damage to enemies.

While Mamako excels at ground type attacks, dealing Double Hit Multi Target Attacks, the swords are completely useless against flying enemies. Masato, on the other hand, can deal Single Hit Primary Target attacks to flying enemies. This makes them the perfect team as Mamako can handle the ground and Masato can handle the air.

Masato Oosuki
She loves her son so dearly that she can be very overprotective over him. She wants to have a closer relationship with him and believes that going on adventures with him will help with that.

Porta was the first person that Mamako allowed to join Masato's party and she even thought she'd be suitable as her son's bride.

Wise
She did not like Wise at the start as she teleported herself and Masato away. However, after finding out about Wise's separation with her mother, she allowed her to join so that she could help mend their relationship.

Medhi
