Senku is a straightforward, confident, and logical individual, who is also aware of the limits of his abilities. His decisions are often backed up by his vast knowledge of science and applying the scientific method. Senku never belittles those who are less knowledgeable than him, however he does have a habit of diving into complicated explanations in an attempt to teach others. However, his enthusiasm for science encourages and inspires everyone around him to do better. Because of his charisma and caring nature, people tend to gather around him, allies and enemies alike. Senku is also able to admit his mistakes, for example if he misses important information, such as when Kohaku pointed out that the north star did not align with north as he claimed, since Senku had overlooked the Earth's precession.While Senku is highly aware of his limitations and will yield to those more experienced than himself, he frequently overestimates his own physical abilities, such as when he offered to carry Kohaku's spring water and immediately collapsed, or when he was overwhelmed by the force of Kinro's attack during a paper shield demonstration. Senku brimming with confidence. Senku has a very logical mind, believing that there is nothing science cannot explain, even if it takes a long time to properly understand any one concept through science. Senku regularly bends the rules, withholds information, and manipulates others to get what he wants. He often acts as if he builds inventions and uses people for his own interest, while actually creating for the betterment of others. Beneath Senku's outward arrogance and manipulative actions lies a genuinely selfless and kind heart. During their decisive battle, Tsukasa notes that despite Senku's apparent cold rationale, his greatest weakness is his inability to abandon his friends, having witnessed his kindness firsthand with Yuzuriha taken hostage. Unlike Taiju, Senku seems apathetic to the prospect of romance. He seemed annoyed when Kohaku worded her praise for him strangely, claiming she had "fallen for him". He strongly discouraged Nikki from developing any feelings towards him. He was also completely unaffected by Amaryllis' attempts to charm him, much to her chagrin. He believes a brain filled with love is most illogical, but he does support the romantic endeavors of his friends, such as Taiju's relationship with Yuzuriha.
