Description
Dasainen is one of three antagonists who make up the Dirt Cheap Trio, serving as a recurring obstacle for the protagonists in Itadakiman. He operates alongside his partners, Yan-Yan and Tonmentan, with the shared goal of obtaining the powerful Oshaka Puzzle before the heroes can. Dasainen is depicted as a 26-year-old ronin, a status reflecting his prolonged failure to gain entry into the prestigious Oshaka Academy, an institution that only accepts confirmed descendants of the Priest Sanzo clan. His pursuit of admission has lasted for eight years, a goal he shares with his two housemates and fellow trio members. He staunchly claims descent from the legendary figure Sha Wujing from the classic novel Journey to the West, based on his family's long-held lore, though the truth of this heritage remains unverified within the story.

In terms of personality, Dasainen distinguishes himself as the primary strategist and intellectual force of the Dirt Cheap Trio. He is often referred to as Yan-Yan's brain henchman, indicating his role as the planner and thinker of the group. Unlike some of his companions, he is not portrayed as purely muscle-bound; instead, his character leans into the role of a cunning inventor and tactician. This aspect of his personality evolves as the series progresses. Initially, his tactics involved commanding demons encountered during missions, forcing these creatures to attack the protagonists. However, influenced by viewer feedback, his approach shifts mid-series to focus on designing original mecha. He then orders the construction of these machines, delegating the building work to Ryuko, a dragon girl summoned by Yan-Yan.

Dasainen's role in the story is to create conflict and serve as an antagonist for Itadakiman, the hero transformed from a boy named Kusaku Magota. As a member of the villainous trio, he constantly devises plots to get the treasure before the Tatemae Trio, the series' designated heroes on the quest for the puzzle pieces. His specific contributions to these plots evolve from direct demon command to mechanical warfare, as his custom-designed mecha engage Itadakiman in combat. Furthermore, he directs Ryuko to transform into the Snail Mecha, also known as the Den-Den Mecha, which the trio uses for transport or as a support unit in battle.

Regarding key relationships, Dasainen is intrinsically linked to his partners Yan-Yan and Tonmentan, sharing their living quarters, academic failures, and criminal schemes. He has a hierarchical and functional relationship with Ryuko, treating her as a builder and asset, assigning her to construct his mecha designs and to transform into a vehicle. His primary opposition is with the transformed hero Itadakiman, whose mechs he repeatedly attempts to defeat. His relationship with the protagonists is marked by consistent failure, as his plots are regularly thwarted.

The development of Dasainen is most notable in his tactical shift from using demons to creating original mecha, a change reportedly driven by viewer feedback. This demonstrates a level of adaptability within his role as the group's inventor. Beyond this change in methodology, his fundamental status as a persistent, scheming antagonist remains consistent. Information regarding his personal growth, emotional depth, or any significant change in his motivations is not documented. Following the definitive defeat of the Dirt Cheap Trio, his ultimate fate or what becomes of him after the events of the original series is not recorded. Similarly, his appearance in later Time Bokan media, such as films, OVAs, or spin-offs, is unaddressed.

The notable abilities of Dasainen center on his intellect and strategic thinking. His primary skill is acting as the brains of the Dirt Cheap Trio, devising plans to outwit the heroes. His most concrete and developed ability is engineering; he is capable of designing original mecha from scratch. While he does not typically pilot these machines himself, his designs are built and deployed as the primary weapons against Itadakiman. He also possesses the authority to command Ryuko, ordering her to assume her transformed state as the Snail Mecha for the trio's use.
