Ascending Alola
At the beginning of Ascending Alola, Kaiko was still a student at the Malie City trainer's school. He wanted to watch his sister's first ever battle, so he rushed to Malie Garden the day that Leinani got her starter Pokemon. When he found out that she had gone to the Malie City gym to battle, he ran there, only to find out that Leinani would not be making her debut battle just yet. He begged Leinani to let him join her on her quest through Ula'ula Island, and after some thought, Leinani said it'd be okay. He then took on the role of guide and planned out their every day.

Kaiko unknowingly missed Leinani's first battle against Enoka Wahilani while he was taking pictures at Ula'ula Meadow. After Nurse Joy mentioned that Leinani's Pokemon had accrued damage from battling, he became suspicious. He was present for Leinani's battle against Guzma, witnessing her first gym battle.

Personality
Kaiko has a strong and optimistic personality. He is a little bit of a control freak, and when he's around Leinani, he grows more timid, but that never stops him from smiling. He enjoys studying and looking at beautiful scenery. When Leinani forgets to scan Pokemon with her Pokedex, he'll do it himself, even if he already knows a lot about the Pokemon in question.

Kaiko loves his sister deeply.

Trivia
