Ndala has had previous youth loans with PSV Eindhoven and Nottingham Forest.
Ndala told Hull's website: “I feel very privileged to come to a club like this. I’m really excited and happy to join the club.
“The manager said he’s watched me since I was playing in the Youth Champions League, and he really showed me that he wanted me to be here.
“I’m a direct, skilful winger; I like to take players on, dribble, create chances and score goals.
“It’s up to me to take this opportunity and run with it. I want to show people what I can bring to the team.
“The Championship is a good level and I’ll take the challenge head on. I’m going to give it my all and try to help the team out in every way I can. I’m ready to show the fans what I can do.”
