1.Contrary to what you could have seen previously, Tomas doesn't have a surname. His amnesia prevents him from remembering it, and he has never officially been adopted.
2.His 'adoptive' mother is Zodiac's biology teacher, Sibyl. She doesn't have a surname either, but in that case, that's only because I'm lazy and haven't fully developed the teachers yet.
3.He's of the Taurus sign, meaning that he's got Earth powers. He specializes in all kind of barriers.
4.He is socially awkward, and usually stays away from people when he doesn't have to talk. While he opened up to other students after befriending Excillam, he still can't understand the latter's optimism or Marina's cheerfulness. He does like to smile, though, as he finds it "quite amusing".
5.His stomach is likely to be a dark hole, never ever filled. When Marina notes that it's one of humanity's biggest mysteries, he simply replies that girls are still the ultimate enigma.
6.He is terribly logical, sometimes to a fault (boldly describing Sibyl's care for him as "only natural" from a mother), while it does give him some nice skills when it comes to scientific studies.
7.His main asset is, ironically, his memory. He could remember the tiniest of details if asked to do so.
8.Tomas has a twin sister (who looks nothing like him, which often happens with twins of different genders), but doesn't remember this fact at all. However, she does, and they just happen to be studying at the same school. Will they ever recognize each other?
*insert the whole second semester's plot here*Alright, that's done! I'm not tagging anyone, because most of my dA acquaintances have already been tagged for this, so feel free to do it if you feel like it~
