==History==
===Ultraman Gaia===
As the chief of the special investigation team "Lizard," which is part of the GUARD Geo Base Intelligence Section, Senuma and his team are responsible for gathering information on various supernatural incidents and anomalies, as well as finding ways to resolve them.
During his initial appearance, Senuma and his team took over the tracking operation for the Wolf Gas, a creature that only appeared at night, as XIG was unable to capture it despite Team Lightning's overnight efforts. When Hiroya Fujimiya appeared at the investigation site, Senuma cautioned him about the danger and advised him to seek shelter. However, Fujimiya responded unfriendly and left the scene.
That night, Senuma along with Gamu tracked the whereabouts of the Wolf Gas. However, Senuma was attacked and rendered unconscious by the creature. Nevertheless, Lizard managed to successfully corner the WolfGas at the top of a tower, forcing it into a corner. With the assistance of Team Lightning, they used tranquilizer darts to bring it down. As dawn approached, Senuma and Gamu witnessed the WolfGas dissipating into thin air.
Following this encounter, when the WolfGas absorbed natural gas and grew into a massive form, Gamu entrusted Senuma with a refined oxidized bomb and handed it over to Team Lightning for launching. With the assistance of Ultraman Gaia, they successfully vaporized the WolfGas and sent it off the Earth.
In the following period, when XIG learned that Kyoko Inamori had modified the monster controller and taken the data without authorization, they handed over the investigation of the previous incidents involving data theft from Aerial Base and Geo Base to Lizard. During the investigation, they discovered that Fujimiya was a suspect in this case. As it was revealed that Gamu had been in frequent communication with Fujimiya, Gamu was subsequently suspended from duty.
As they received orders to pursue Fujimiya and closely monitor the actions of Reiko Yoshii, who was reported to have been kidnapped, Senuma and his assistant followed them closely on the road. However, when Fujimiya and Reiko's vehicle skidded and fell into the sea, Fujimiya transformed into Ultraman Agul in a critical moment. He rescued Reiko and left the scene. Before departing, he unleashed a burst of light to attack them.
During the battle between Ultraman Agul and Ultraman Gaia, Senuma attempted to take Reiko away from the scene to avoid being affected and warned her that it was not something ordinary people could handle. However, Reiko countered, arguing that it was precisely because they were human that such situations arose.
In the following period, Senuma handled multiple missions involving supernatural events. This included delivering ancient documents related to Kijuro Mato for investigation by XIG. Additionally, when Gan-Q appeared, he unexpectedly rescued Shusaku Sawamura, a descendant of Mato, at the scene and provided protection.
Furthermore, due to several monster attacks occurring in the city, Senuma also conducted investigations regarding these incidents. When Gamu and his friends encountered Wolf Gas on their way home from the gym, they were able to successfully defeat Wolf Gas with Senuma's timely assistance.
After a period of time, the Anti Airspace Laser System, a new weapon developed by GUARD, was breached, resulting in the modification of the system's data. Based on the testimonies of the personnel at the scene, Fujimiya, who had been missing for a long time, was identified as the mastermind behind this incident. As a result, Senuma and Gamu initiated an investigation in an attempt to apprehend him. However, when they arrived at the scene and located Fujimiya, they were confronted with the situation where he threatened them with a bomb. Helplessly, they could only watch as Fujimiya escaped.
When Queen Mezard initiated an assault on the KCB headquarters, Senuma who happened to be in close proximity, was temporarily under her control and used to attack Gamu. However, after Gamu rendered him unconscious with a fire extinguisher and Gaia intervened to halt Queen Mezard, Senuma regained his normal state. 
After the mentally distressed Fujimiya was admitted to the hospital, Senuma and the others received orders to protect him. They requested Gamu, who was present at the scene, to return, but after Gamu's persuasion, Senuma agreed to observe Fujimiya for a while longer.
However, when Σ-Zuigul reappeared and kidnapped Gamu, Senuma was ordered to remain at the scene. While attempting to take Fujimiya away, they were attacked by Σ-Zuigul, forcing them to let Fujimiya go. Eventually, they successfully rescued Gamu from the crucifix and witnessed Ultraman Agul regain his power and successfully defeat Σ-Zuigul.
