Amado is reserved and does not show too much emotions outside from being calm. Unlike Delta who is shown to be wrathful, Amado is relaxed. Only time Amado shows surprise is when Delta angrily kicks open the lid of her containment damaging it. Amado seems to be loyal member of the Kara organization and is shown to be practical. Amado also does not seem to show any level of empathy for the child test-subjects and does not show any compassion or care for their deaths by having Jigen force the kama seal on them. However, he does think that the number of children dying in their attempts mean that there is no improvement in their goals.
One day after gathering all the abducted children, Jigen and Amado both held the children in plastic containers filled with water. Amado would help Jigen force the kama seal onto each test subject to test their strength and whether they can handle the seal. They would do this for the purpose of getting a new vessel for the Kara organization and for Jigen. However, for each child that Jigen force the seal onto the child would die from the seal. Amado expressed a level of concern for their progress in getting the vessel since almost all the children died but Jigen reminds Amado that finding the vessel is very important. The last of the test subjects, Kawaki, was successfully made into the vessel for Kara. Amado would then extensively modify Kawaki, implanting countless microscopic Shinobi Wares throughout his entire body and altering his body tissues to a cellular level to grant him powers unrelated to Kama. He was also in charge of Kawaki but Kawaki managed to escape from him.
Amado was mentioned by Jigen to have been assigned to another mission that is strictly hidden, with Jigen refusing to discuss the details with the other Inners. Amado appears in a room that contains replicas of Delta to help revive her after she ended up dying from her battle against Naruto Uzumaki. He did not like Delta's temper when she kicked open the pod after her revival and remarks on her anger. Amado overhears the conversation from Delta about the progress at retrieving the vessel and that Boruto Uzumaki contains the kama seal.
When Jigen returned from his battle against Naruto and Sasuke, Amado treats Jigen and tells him that he will be back at full power in the next few days.
