• Portal — yes Kiichi!! is a Japanese manga series written and illustrated by Hideki Arai. It was serialized in Shogakukan's seinen manga magazine Big Comic Superior from July 2001 to February 2006, with its chapters collected in nine tankōbon volumes. It follows the story of Kiichi Someya, from his childhood through to adulthood.

Kiichi Someya was raised by his parents to be free and honest. This led to him developing a violent temper and being prone to outbursts whenever he was displeased. His aggression frequently causes problems at kindergarten, though his parents attribute his behavior to strong personal conviction and never scold him harshly, instead raising him with affection. One day, however, Kiichi witnesses his parents murdered before his eyes by a random assailant—an event that drastically alters his life. Following the incident, Kiichi disappears and ends up living among the homeless. After a period spent alone in the mountains and eventually being taken into protective custody, he learns the importance of surviving on his own. By the time he reaches elementary school, a bullied classmate named Misato Saji confides in him that her father is forcing her into child prostitution. Together with his classmate Keiichiro Kai, Kiichi becomes deeply involved in this case, which concerns powerful figures. Ten years later, Kiichi co-founds an nonprofit organization with Keiichiro, the Kiichi's Company, advocating the motto "Be honest" and carrying out various forms of aid work. His popularity and influence grow so great that they surpass even those of the sitting prime minister. Gradually, however, Kiichi and Kai grow apart. Following a decision to support Kurita Refrigeration, a company brought to the brink by a scandal involving fraudulent labeling of imported beef, Kiichi breaks ties with the company. Kiichi eventually meets the murderous terrorist group known as the Haramita Theater Troupe. There, he falls in love with the group's leader, Aya Tanaka. Driven solely by his feelings for her, Kiichi takes over the group and commits shocking acts.
