"How about becoming my little sidekick from today onward? Then I'll forgive you!!!"
-Si Ang
Si Ang Anderson (Sian Anderson), originally named Sian Evan, was Test Subject No. 110.
His primary innate ability was X-Ray Vision, which allowed him to see the soul within a person's body and the extent of its deterioration. He was a walking human X-ray machine.
Si Ang's hidden ability was astral projection, but he could only use it once.
Of all the test subjects, he was the only one with a second innate ability.
He was also the only mutated test subject in the entire institute, just as exceptional as Richie.
The researchers had tried every possible way to discover Si Ang's hidden ability, but he simply refused to tell them.
Even Si Ang himself did not dare use it.
If he failed to control it properly, he could lose everything.
When Si Ang learned that Richie was not from this world and could not stay by his side, he made plans to travel to Richie's world.
First, Si Ang asked Richie for his original name and address, and had him draw a picture of what he looked like.
Si Ang did everything he could to memorize them, then pretended to lose his memories when Richie hypnotized him.
Only then would he have a chance to search for Richie.
Si Ang did not tell Richie about this ability, because he could not be certain he would actually reach Richie's world.

He did not want Richie to suffer the pain of longing
