Fuu

Background
There's four heroes that got summoned (Meiko, Yuuki, Seigi and Fuu). (16-42)

Shy kid who couldn't hold conversations well. Hero Fuu has trouble communicating. (16-44)

His ability was of scouting type, yet for some reason, he tried really hard to learn magic.

Hero Fuu who excels in scouting--or to be more exact, assassination.

Even though he's alone. He seems to have the habit to refer himself with 'we' and 'our'.

The way he could suddenly scream out loud in between his usual blurred voice is probably another habit of Hero Fuu.

Hero Fuu's boiling point seems to be unexpectedly low.

Equipment

 * A bracelet made from Blue Crystal (It's a terminal device bracelet for City Core that originally shouldn't have fallen onto a hero's hand.)

Plot
His aptitudes for elemental magic were apparently not good, but he is skilled in Sou--Summoning magic. (16-44)

Unlike with the other heroes, apparently he went to Hero Dungeon once, got frightened, and refused to go back.
