- "It's heavy, don't drop it!"
- ―Delin telling Ryo not to drop the heavy crates.
Delin is good natured, works very hard and doesn't take things too seriously. He doesn't have any future plans. It seems he is satisfied if he can earn enough money to live each day out.
After Joy takes Ryo Hazuki to work at Fortune's Office for the first time because all his money was stolen, Ryo can work with Delin at anytime to earn extra money by asking either him or the boss Gonglin Sun about a part-time job (When near or locked on to them, press the Y button, then select "Part-Time Job"). They will need to move all the heavy crates in the warehouses together.
Later on, Delin teaches Ryo the Brawling Uppercut move if he works with Delin while he's earning $500 to meet Wuying Ren, or after he already meets him (If the Command QTE fight with Ren is succeeded), because he's afraid if he helps Ryo fight Ren, his gang will come after him. So he thought he could help by teaching him a move.
If Ryo says goodbye to Delin before he leaves Hong Kong for Kowloon, Delin will feel upset, as he feels he and Ryo made a good team while working for Fortune's Office.
- If Ryo continues to practice the Brawling Uppercut move after he masters it, Delin will show him how to do the move again, but when he takes a step back, he falls into the sea.
- Delin's zodiac sign is Cancer and he has a A blood type.
