Lero-Ro

''"I'm now going to the 77th Floor. If I go there...I may be able to find the truth." - ''Lero-Ro to Quant

Lero-Ro is a Ranker and an Administrator of the second floor. He is supposedly smarter than Quant, and is skilled in the use of Shinsoo. He is also the Light Bearer trainer. He is fairly old, older than Yuri Zahard, as he stated that Anak didn't live up to a princess's chaotic expectations like Yuri Zahard did.

Appearance and Personality
Lero-Ro is a tall human-looking individual with blonde hair and two black spots under his eyes. His choice of clothing is that of most test administrators: a white lab coat with black trousers and gloves.

He appears to be a fairly collected and easygoing person. He is somewhat inquisitive about people. He had trouble considering whether or not he should let Koon pass the hide-and-seek test; although it was obvious that Koon was brilliant, he also considered Koon dangerous. Yu Han Sung noted that due to his intelligence and curiosity he could be quite hard to manipulate. He is a shrewd individual, realizing that his superiors are hiding something about the truth of the Tower, the Irregulars, and Baam.

Plot Summary
Lero-Ro proctored the tests on the Second Floor with the other administrators. He introduces himself to the Regulars just after they team up, then flings a Shinsoo barrier at them. When Baam was not pushed back by the barrier, Lero-ro realized that he had "another monster," and agrees to let him pass. He sat with Baam and watched as the other Regulars try to get through the barrier. They made a bet over who would pass through the barrier first, with the winner having the opportunity to ask the loser a question. However, they both bet on Anak and both proved to be right. Lero-ro conceded the bet to Baam, who asked him what an Irregular was. When all the Regulars had gotten through but three, one of them loudly complained, causing Lero-ro to shock him with Shinsoo, to prove that he could not advance. Afterwards, he left them to the next test.

He next appears during the Crown Game. He watches Anak's fight and states that although she was strong, she was a disappointment compared to Yuri - although her weapon was a bit dangerous. When Anak attacked Baam to try and get the Black March, Lero-ro intervened and arranged things so that if Baam's team won the Game, they would get the Green April, if they lost, Anak would get the Black March.

Later, he serves as the trainer for the Light Bearers. He watches the hide-and-seek test silently, and saw Koon's whole scheme through his Lighthouse. He had difficulty deciding what to do with Koon, which Yu Han Sung only made worse by talking to him in a cryptic and menacing way.

Later, Koon came to him to reveal that someone other than a Ranker had influenced events in the previous test. Leo-Ro took this into consideration, and spoke to Yu Han Sung about the purpose of the second floor. He notes that water left alone would "stagnate" and that it was about time the Tower got some change.

As of Chapter 78, Lero-Ro has quit his position as an Administrator on the second floor and intends to go to the 77th floor, where the headquarters of the Walhaiksong resides. He tells Quant that there he may be able to find the "truth".

Powers and Abilities
Physical Strength: Lero-Ro is much stronger than he looks. He was able to hold back a two-handed swing from Anak's weapon with just one hand, without seeming to exert much effort at all. He may have used Shinsoo to do this.

Shinsoo Barrier: Lero-Ro can create barriers of Shinsoo, which push weaker beings backwards, and will stop those who cannot handle Shinsoo from coming through.

Shinsoo Density Control: Lero-ro can increase the density of Shinsoo around him to incredible levels, enough to shock a powerful Regular unconscious just by getting near him.

Lighthouse Control: Being a Light Bearer, Lero-ro can control Lighthouses.
