He thought his skill was useless... but it was actually an ecchi cheat skill!?

Lark, a young boy who dreams of becoming a great adventurer, possesses the seemingly unfortunate skill "Color User," which only allows him to launch ink from the tip of his brush. Despite his desperate efforts, Lark is kicked out of his party due to the perceived weakness of his skill.

One day, he meets Arian, the leader of the S-Rank party [Valkyrie], and learns the true way to use his skill. Its true identity was... "The Strongest Enhancement Magic"!

However, the activation condition is to draw the magic directly onto the bare skin with his brush. Every time Lark touches the undressed Arian with his brush, an ecchi gasp escapes her lips, making the innocent Lark's heart pound! Furthermore, he ends up having to cast enhancement magic on all the beautiful members of the [Valkyrie] party...!?
