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 have a strong comradeship. Though not much is seen, the two are seen together mourning for Bols, and Run silently warns Wave to be careful regarding Wild Hunt due to Syura being the Prime Minister's son. Run later confides to Wave as to his true intentions regarding his time in the Jaegers, that being avenging his class which were massacred by Wild Hunt and changing the empire's ways from within.

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.
