Tetsuo Shironuma

Tetsuo (Shironuma Tetsuo, 城沼哲雄) is the main and only possible romance character in sweet pool.

His appearance in Youji's life is immediately deemed a troublesome one, and while for the most part outwardly harmless is quite strong.

While Zenya is understandably considered an oddball due to what information has drifted around about him, very little to no information is known about Tetsuo, which makes him very intimidating and difficult to understand. His lack of enthusiasm and speech does not help the matter.

Personality
Tetsuo expresses little to no emotion during casual interaction or conversation. Even in conflict, he holds a straight face and stoic exterior. He's highly intelligent and excels in all of his classes, making him an admirable and straight A student.

He's aloof, soft spoken but strangely, not very shy at all. He simply is a man of little words. He does, however, have an inconvenient habit of not being completely straight forward and to the point at times.

Relationships
Youji Sakiyama - From the very beginning, Tetsuo has shown interest in Youji for unknown reasons. As if drawn to him naturally, he is often not far away when at school. His relationship with the older teen is slightly strained, as his directness and physical methods of communication are not well received. His own feelings on Youji, while not spoken, can easily be seen as a mixture of curiosity, sexual interest and possessiveness.

Makoto Mita -While Tetsuo initially has no ill feelings for the teen and for the most part continues with his disinterest towards him throughout the story, the feelings are not mutual. Makoto is often on his toes and bristling at his classmate and sees him as a threat. Tetsuo does not understand nor care as to why the smaller male is so defensive and angry with him all of the time.

Zenya Okinaga - Tetsuo dislikes Zenya. Even though he rarely if ever outwardly expresses it, it's rather clear in his method of communication and their interactions that their relationship is not a good one in the slightest. Zenya often antagonizes and pushes Tetsuo for reactions, and for the most part, Tetsuo does not respond. Enough pressing and one of these days, though, Zenya may just get the reaction he wants, though most likely not in the way he anticipates.
