You have been sent this because you asked what my name means.
君は死にません (kimi wa shinimasen) means “you will not die.” The ません ending is the polite negative, will NOT.
Now say that last part out loud: ま-せん → “ma-sen.” That せん (sen) sounds very similar to SHEN. So I spell it 死にまSHEN, similar sound, name contains the champion I one-trick.
This works well for Shen because he shields his allies and makes them not die. So 君は死にまSHEN = “you won't die, Shen's got you!”
