|First Appearance||Shin Megami Tensei II|
Okamoto is a non-player character from Shin Megami Tensei II. He is the owner of a fighting gym in the main town of Valhalla, and the man responsible for saving an amnesiac Aleph from being killed by an horde of demons.
Judging by comments made by other NPCs about him, Okamoto seems to have something of a gambling problem (spending all the money he and "Hawk" make on the casino); also, he is always borrowing money from someone.
Shin Megami Tensei IIEdit
After seeing how he defended himself, Okamoto took Aleph under his wing, naming him Hawk, and began training him to be a Gladiator in order for both of them to achieve enough money to leave Valhalla. He is, however, freed of all his debts after Aleph is titled Champion of the Colosseum, and the gym of his rival Haneda is left under his management, where it gains great popularity.
- According to Kazuma Kaneko Works III, Okamoto is modeled after (丹下 段平) from the comic .
- The janitor of Karukozaka High School from Shin Megami Tensei: if... is a reference to Okamoto in that they are identical appearance-wise except for the color of their clothes. The janitor can later be found in the World of Gluttony's Casino as a reference to Okamoto's love of gambling.
- In an inaccessible line in Shin Megami Tensei II, it is revealed that Okamoto was quite the capable fighter in his past, taking on former Valhalla Colloseum Champion Feather Adonis in a well-remembered fight.
