Wave/Relationships

Jaegers
Kurome : Kurome is perhaps the member of the Jaegers that he is closest to. They seem to stay with each other as to not be alone but over time he develops a rather strong caring bond with her, to the point she confides in him she is scared of being disposed of for being seen as weak in battle following injuries. Both are seen to get along quite well. He has silently declared that he'll protect her, having done so several times, such as taking a hit that would've proven fatal for her it it had impacted her, as he said by the force could have even killed him as well. He is also protective of Kurome and is seen to care for her equally, such as when protected her from Syura who tried to take Kurome as a sex toy. Later on, Wave develops romantic feelings for Kurome. He cares for her greatly, most notably when it comes to her health.

Esdeath: He is respectful of his leader, but at the same time, is also terrified of her, especially when it comes to failing her. Esdeath has noted that she regards Wave as incredibly strong and talented, almost perfect.

Bols: Though initially frightened of Bols' outside appearance, Wave had a strong connection to Bols, and understood the man's gentle nature behind the mask. Bols' death was one of the most memorable events in Wave's life, causing him to swear to avenge Bols during one of Night Raid's attacks and when he attacked Syura for killing Bols' family.

Run: As a fellow Jaeger, Run and Wave had a strong comradeship. Though not much was seen, the two had been shown to care about each other, with Run comforting Wave after Bols' death and holding him back from getting into trouble with Wild Hunt due to Syura being the Prime Minister's son. Run later revealed his past and true intentions to Wave. After witnessing Run turned into a corpse puppet, Wave was greatly saddened by seeing his friend reanimated and enslaved, wishing for him to rest in peace instead.

Wild Hunt
Syura: Wave openly detests Syura, mainly due to Wild Hunt's methods in dealing with criminals, and Syura asserting himself due to his father, the Prime Minister. He was further provoked when Wild Hunt killed the family of deceased Jager, Bols, and when Syura harassed Kurome.

Night Raid
Tatsumi: While only seen briefly, Wave immediately warmed up to Tatsumi and liked him as he was the only other "normal" person in Jaegers and he saw a lot of himself within Tatsumi.
