The fusion of a male and a female..and no it's not that "thing"; Ningen Fushin episode 4 Impression

Bond is the one of the main theme that describes most anime and manga. The meeting between people who shares the same vision despite of differences and as they grew closer, the friendship flourish introducing the term we all know as "nakama power". This nakama power enables them to overcome hardship and eventually, they defeat or conquer the big bad. Similar to the other anime establishment, Fushin Ningen also shares similar traits as the fouru human hater started to open up to each other despite a bit of a little rife between the ladies before. I think the usage of "bonding" moment it in anime had already been redone so many times; therefore it needs a deep characters building to keep it more ⚖️ and entertain the audiences. One piece of advice is simply putting smart comedy or a good twist or two on it so people may overlook the "generalism"

Your very existence itself is the proof that we didn't need logic on this anime

This episode continues right  focuses the character development between Nick and Curran. In contrast to the last episode, it focuses on Nick's point of view now. The main story so far is the survivor get important quest to find the Legendary sword; the sword of Bond by the Obasan Guild master. The squad of Survivor head to the bond's dungeon where the sword located and it doesn't take them long to reach the sword pedestal. Unfortunately, after a brief conversation with the sword; the defense mechanism start initiating the sword's guardian; the Amalgam Golem. While Nick is busy trying to keep the guardian attention away from his teammates,  the sword asks Nick to focus on one of his party member (which is currant) and tells Nick about the fusion skill which enables him and Currant merging into one individual. It may be possible for more combination in the future as the sword chooses Currant after looking thoroughly to Nick's party member. Using the sword fusion, we may see a combination like Nick x Tiana or Nick x Zem.. Heck, maybe we can even see the hot and cold fusion too 😂. The ideas of fusion pretty much mimic the one in Dragonball (there I said it ) expect that in this anime, the fusion between a man and a woman; not to mention that she is a dragonkin, is possible.

Nick repeat after me..." Sosei Gattai !! AQuArioN!!!

My guess about Curran's insistence on keeping the memento despite it makes her remember about Kalios' betrayal is right all along. Even if Kalios stole the King Dragon Gem, the memories that they shared during their time travelling together ran deep inside her consciousness. This sentimentality thankfully balances with her realization that she has another party leader now. While still holding a tiny hope that one day Kalios will be back to his old self, she is pretty much threw away the past memories. This episodes completes Nick's curiosity about the memento and whether it's means something to her; after Curran explains about the necklace and how it's ok if she lost it. Therefore, having it got accidentally scratches by Nick is not a big deal for her. Curran resolution's to left her lingering past; opening herself to Nick along with Nick's relief after hearing from her are what enabling them the sword's skill fusion; merging them into one individual (a male paladin with a reddish orange hair). In one note, the Fusion's strength is on another level as it can deliver a deadly blow to the Amalgam Golem in a one hit only.

I'm neither Nick nor Curran..call me BOB😂

The sword of bond; as it name suggest represents the theme of today episode as the four characters overcome a crisis together and develop their relation up to another level. Just like in the real world, difficult times built comraderies and their fight against the Amalgam Golem strengthen their bond further. At the beginning, they met with the talking sword; which looks like a handle without a blade tips, claimed that it is the sword they've been searching for. The funny things is that despite of the sentient sword talks using a Japanese older accent yet, it's human form resembles a youngster with white hair. There is still not many explanations about the sword 's origin and how it's got a soul inside but more or less, it can be revealed on further episodes.
