Hydro Hand

Hydro Hand (水流操作) is a lineage of psychic powers involving the manipulation of the flow of water. A limited derivation of Telekinesis. Regarding the naming, it probably belongs to some broad category attached by Academy City. Users include the Level 3 Wannai Kinuho.

Shown applications include removing dirt of a drained pool without the use of a deck brush by collecting the little remaining water and rolling it up until waist-level. It is enough to make a 10 courses-wide pool entirely clean.

Incidentally, it seems that Hydro Hand powers are not uncommon in the Tokiwadai Middle School's swimming club.
