Nendo has a simple way of thinking, but because of it, Saiki is unable to read his mind. Because Saiki is unable to detect Nendo's presence, Nendo is the only person who is able to sneak up on Saiki and making him think he will someday be a dangerous foe.
Nendo believes he is a friend of Saiki, but this is definitely not the case as Saiki despises Nendo. Saiki would often compare Nendo to a bug, as bugs are one of the few animals that Saiki cannot read the minds of.
