Tetsuji Suwa

Tetsuji Suwa (諏訪 哲司, Suwa Tetsuji) is the Deputy Director of Tingarla Aquarium.

Biography
When Tingarla opens, Suwa becomes Kukuru's marketing manager, giving her the nickname, "Plankton".

Personality
Suwa presents himself as stern and serious at his job, always making sure that everyone at Tingarla is doing their own assignments, even directly calling out Fuuka, who doesn't work in marketing, when she worries about Kukuru. Though he is consistently tough to employees, this all stems from guilt that he never let go of due to what befell the animals at another Aquarium.
