Oh my. Tanaka can be such a pain sometimes. Points to Okuyama for keeping his cool and not taking the bait for the most part. Having Tanaka, basically an ignorant amateur, hover over him and question his competence in his area of expertise - time and again - must have been at least a little aggravating. In retrospect, it's funny how Tanaka complains about finding him a difficult person to get along with, like... Are you sure it's Okuyama's attitude that's the problem? Are you really really sure?
For that matter, when the others join the team, he doesn't hit it off with them right away. He can be civil with them, but mostly keeps to himself.
He listens to what others have to say, but he himself doesn't contribute to the discussion.
Again, he doesn't exchange a single word with them. He does try to earn extra points with Satou though by finishing his sentence for him and then proceeds to kinda smile at him, stop being so cute. Not the first time and not the last he quotes him word for word, proving he always listens intently.
Staying on the sidelines, once more. Probably lost in thought, imagining everyone who wronged him meeting an untimely end soon, and who can blame him?
To be fair though, they didn't exactly leave the best first impression on him, considering their first interactions consisted of pointing out his faults.
It's no wonder in the beginning he feels inadequate and inferior next to them - Okuyama with his intelligence, knowledge and computer skills, Takahashi being a natural at shooting, Gen who got a steady head on his shoulders. How is he supposed to compare? At this point he's still lacking in self-esteem, so he immaturely lashes out in the only way he knows how - by trying to put others down.
As a result, it takes him a while to warm up to them. But he grows as a person, gains more confidence acting as a second in command and eventually lets his barriers down around others.
Feeling comfortable enough to partake in friendly teasing.
