The hero of Shin Megami Tensei: Devil Summoner, Raidou is, well, a devil summoner of the Raidou Kuzunoha legacy, the fourteenth to carry the title (like how Hiko Seijurou of Rurouni Kenshin isn't actually named that, it's a Master-To-Student name). He's a police detective in the Taisho era of Japan, 60 years after the Meiji (so 50 years after Rurouni Kenshin takes place). As was mentioned before, he's a Devil Summoner, and that was very difficult to figure out.
The end result is that what Raidou does is capture stunned demons and force them to work with him, brainwashing them into allies. This is represented by the Devil Tubes, which are a capture tool (a la Pokeballs). What Raidou does is stun a demon with his Handgun's variable descriptor Stun by swapping the descriptor to the one that would hurt the demon most (so for a fire enemy you put in ice bullets, and vice versa), and then use the Devil Tubes to capture the enemy in the dimensional space and permanently brainwash them. They sit in that dimensional space until called upon. This dimensional space is functionally unlimited, and Raidou can hold as many demons as his little heart desires, with the following restrictions:
The demon cannot be more powerful than he is (i.e. above PL 10).
He can only have one of each demon (so no double-pikachus or anything).
These restrictions ensure that he has some powerful abilities without being too dangerous. Note that the 'Oni' descriptor refers to the Japanese demons (as do all my Demon references), and thus encompasses a large number of enemies normally immune to crits, like Zombies and other undead.
