Seguro

Seguro (セグロ) is a minor character in Wadanohara and the Great Blue Sea. He is a yellow-bellied sea snake and close to Miyura.

Physical Description
Seguro possesses lemon chiffon-yellow eyes with narrow black pupils. Based on a yellow-bellied sea snake, Seguro has a distinctive bi-colored pattern, having a golden-yellow underbelly with an extremely dark brown (off-black) back. At the end where his tail paddle begins, the pattern begins into a more wavy pattern. He is often depicted smoking.

Personality
Seguro seems to be someone who is focused on his friends at all times and can hold a silent concern or worry over them, as seen when Helica had gone missing, and Miyura and him had set out to find her. Seguro tries to stay brave and coolheaded about dangerous situations, despite the fact that he is at unease. When being surrounded by Sea of Death enemies, he is quick to shoot down Miyura's pessimism.

Despite his intimidating glare, the sea snake has a generally friendly behavior to those he knows, although the sea snake doesn't hold back on referring to someone harshly when aggravated, referring to Helica as a "buffoon."

Seguro, unlike his friends, is not as passionate when it comes to expression and has a range of more subtle expressions such as a small smile or a more prominent frown. Undeterred by the natural glare in his eyes, Seguro is more languid with his emotions, this is further shown when Helica and Miyura were much more vehement towards the Totsusa invasion whereas Seguro wasn't as much.

As for his likes, he likes beer, as stated by his biography in the Bonus Room, and can hold his alcohol better than most others. He also likes cigarettes; this is further shown in the Bonus Room where he is smoking, as well as his character portrait where he is drawn with a cigarette. Though he appears to prefer smoking away from others.

Background
In the past, Seguro may have been around prior to the war or during the war between the Blue Sea and the Sea of Death, given how he was able to recognize the Red Sea as well as the others as a "familiar enemy."

Miyura
Miyura is often seen with Seguro, if not always; the two are always seen together and appear to have a close relationship with one another, Miyura going as far as calling the sea-snake her "main squeeze" in a drunken daze. Seguro often yells at her, along with Helica, although it may be over her clumsy actions and foolish behavior. Miyura often gets into his business, but he quietly enjoys it. Seguro can be harsh at times, but only when when there is an irritant to be frustrated about.

Helica
Helica and Seguro are close friends with each other, as well as Miyura. They're seen together often, both referred to as "squeezes" by Miyura. When blinded by rage at the sight of her enemies (Totsusa Soldiers), Seguro is one of the few who attempts to calm her down. Knowing that Helica is a lightweight drinker and becomes boisterous when drunk, Seguro expresses concern over her drinking but appears to drink with her regardless.

Idate
Idate and Seguro are acquaintances, seen to have met each other in the Bonus Room video "Love to Stroll" post-game. The two have a neutral relationship; Seguro appears to be disinterested in getting to know Idate, which is evident when he questions the other, as well as being discomforted in Idate's presence. Idate had first interacted with Seguro by inquiring as to where he found the underwater cigarettes, in which Seguro answers; the conversation between the two is brief and ends shortly.
