Which Tekken 5 side-story mode focuses solely on Jin Kazama?

Which Tekken 5 side-story mode focuses solely on Jin Kazama? Devil Within is the answer.

Devil Within is a Tekken 5 side-story mode centered exclusively on Jin Kazama. Instead of standard one-on-one matches, it plays as a 3D beat-'em-up with platforming elements, labyrinthine stages, enemy groups, and bosses. Jin investigates a trail connected to his family and the Devil Gene while battling through the mode's environments.

The mode continues the Tekken Force-style action format previously used in Tekken 3 and Tekken 4, but it limits the playable focus to Jin. Players can also transform into Devil Jin, connecting the gameplay to the character's developing storyline and his debut as a playable form in Tekken 5.

Tekken Bowl is a separate minigame, while Tekken Force belongs to earlier installments. Arcade Quest is from Tekken 8, so it cannot be the answer for a Tekken 5 question. Devil Within is therefore the single canonical choice.
