Lien is one of Ryuji's party members. Clad in heavy armor and seen by his "friends" as the cool and quiet type. However, he is not quiet on the inside, very much the opposite.

In his own head his thoughts are filled with hatred for Ryuji and tons of thoughts that make it difficult for him to talk outloud without it all coming out as a mess of gibberish. When interacting with other characters, he'll almost always be silent or let out a grumble.

However, when delivering his lines aside, there's a lot of pent up hatred and frustration.
