Shiro’s favorite color is actually purple, so it’s fortunate he landed himself the black lion. He thinks about this quite often, but will admit it to no one, as it’s a silly thing to think about—what do colors matter when the fate of the universe is at stake. Kuron also loves purple, but is a little more open about it, in that many of the accessories in his room are mysteriously purple after “Shiro” returns from Galran captivity the second time. When Shiro returns, inhabiting the body of one of his clones, he does not change the décor, since he genuinely likes it.
Having essentially raised Keith, he sees the guy as a son or brother, initially (after returning from the Kerberos incident). Everyone on the Voltron team becomes his family, of course, but Keith is special to him. His strong feelings begin to grow, of course, and in general, develop into a deep, abiding love and respect. That these feelings may be amorous remains to be seen.
Takashi Shirogane considers himself homosexual, but would never just talk about it… he does not believe one’s orientation/gender expression is a casual topic—not that he finds it offensive, but he prefers to play things like that close to the vest. In this era, it’s not odd or unheard-of, or even remotely taboo; he’s just a fairly private person.
He loves the term “space dad”.
When Keith offers Shiro his father’s clothing to wear after the rescue from the crash site, Shiro is, at first, hesitant to take them. He does not feel worthy of stepping into a role that he refuses to acknowledge he’s been playing for years and Keith reminds him of this. Shiro is a man of pragmatism and reality, however, and in the end, he settles into the role of “space dad” and team leader with unpracticed ease.
Shiro is self-conscious of his body. He is covered in scars and the Galra robot arm doesn’t help. Staying clothed around people is priority 1.
The eyeliner used to take him a while, but now he can whip it on without a mirror. Everyone is jealous.
Shiro is 100% a gay disaster.
He is not very good at giving/receiving romantic gestures. His words are his most powerful tool and sometimes that’s all he can offer, but as far as flowers, chocolates, gifts, and such go, he is genuinely terrible at making such leaps of faith. Similarly, he never knows how to respond to them properly. Part of him genuinely believes he does not deserve that kind of affection, because
He is very much aware that his mind and heart are always thrown completely into his work, no matter what it is… From studying and eventually teaching at the Galaxy Garrison, to commanding Voltron and then being the rear-guard for the Voltron Coalition, Shiro’s greatest passion is always in whatever cause he has chosen to take up. This can be tough for S/Os, he knows, but he genuinely doesn’t know how to stop.
Adam’s death is a heavy blow to Shiro, who, while not expecting to still be affianced upon his return to earth, had at least hoped to see him, to explain and apologize and maybe mend whatever relationship might be left. He feels there are a thousand things left unsaid, a million thoughts and feelings passing between them that now cannot because of that ever-present barrier of death.
Shiro remembers much of what his clone did and said while he was trapped in the Black Lion’s consciousness. This causes him some serious disorientation whenever events are brought up which took place during that time, because he is seeing through two sets of eyes, one in the Castle of Lions and one aboard the Black Lion with Keith.
The reason “Shiro” continued to roll a Paladin in the DND episode is because it is all he knows, all he was designed to do: Be The Black Paladin. The cloning process picks up his life at a critical time, in adulthood, when he has become a battle-hardened warrior, Champion of the Galra arena. He knows that period of his time is supposed to be painful, because it is painful to the real Shiro, so he clings to the literal only thing he knows for certain: he is a paladin of Voltron.
He is very satisfied in his new role as commander of the Atlas in support of Voltron. Keith is leading Voltron, as Shiro asked him to do, and he has a bird’seye view of the battlefield, an important, strategic position for him to take up. He fits well into it and is only mildly surprised that the rest of the Garrison staff have fallen so completely in line with it. He is a natural-born leader, and though that leadership has not placed him back at the literal head of Voltron, his servant-leader attitude allows him to be content where he is. This is not about glory: it is about justice, victory, and survival.
He misses his black/white hair and wonders if the gray will take a dye. Much like his love of purple, Shiro knows this is a silly and vain pursuit, yet the thought persists.
