HI YES HELLO this is my theory on why I believe Yumoto Hakone is the strongest Battle Lover and no one can prove me wrong unless you too think something different and in that case, okay I believe you.
In BOTH Seasons, Yumoto gets his powers FIRST.
So, let's ignore the fact right now that his brother was Maximum Gorar (until later) and let's look at s1 as a whole. Already in s1ep1 we see Yumoto naturally adapt to being a Battle Lover and the others note this as well. He even punches the monster after using the Love Attack for the first time and this kid IS NOT someone who hits people. (He does throw a kick too in s1ep5)
Then if we go to S1ep8, Yumoto shoots the monster out of their house to the SCHOOL.
In the s1 finale, Yumoto blocks Kinshiro's attack with Atsushi like it's basically nothing and they only get pushed back due to the force of it all (Although you can see some strain on his face, but Yumoto's attack seems even stronger than Atsushi's here).
Yumoto even blocks Gora's attacks like they're nothing with his own Love Stick and even the Love Staff. He even takes care of Zundar and Hireashi on his own for a hot minute.
Let's skip to s2, we see right away that Yumoto is pretty strong (Atsushi does outshine him a tad in the first ep). Yumoto's strength is shown a lot as the season goes on
In s2ep9, Yumoto's own attack evolves into the Love Sprinkle (Which we don't see again, BOO), this attack is JUST as strong as the Love Attack but not healing enough on its own as True Love Fountain
The s2 finale i've talked about tO DEATH but I want to really focus on his attacks in s2ep11, he is the first to attack but the last to fall. He withstands more attacks than the others it seems and ONLY falls once he is attacked with basically bombarded with a super strong attack by the VEPPer
And we all know berserk Yumoto so I'm going to skip the photos for this scene (lol), we see Yumoto panic so hard and so much that we see actually what happens when a Battle Lover gets super deep into their emotions. My favorite thing too, WHEN Yumoto turns Ultra More Better, Zundar AND Dadacha scream, "NOT AGAIN!" and Kinshiro actually looks very HOPEFUL when Yumoto does and is stunned (KinMoto fans REJOICE)
Yumoto is such a badass in the OVA when they let him. NOT ONLY does he block attacks with ease but he EVEN helps the twins and IF YOU WATCH, in the OVA, Yumoto NEVER talks to them or even stands near them until he protects them which starts the final stages of the fight. We see how Yumoto can throw out strong attacks and can block EVEN stronger attacks.
He even instigates healing the monster when they're in civilian form <3
TO ME, Yumoto is the strongest Battle Lover, EMOTION wise. Atsushi does note that Yumoto's powers come from his own emotions during the berserk scene. Even when he's knocked down, he usually can get right back up if needed.
In fact, I do enjoy the scenes when Yumoto DOES get knocked back, because it does show, even someone as powerful as Yumoto can fall before getting back up. Yumoto is supposed to be this show's Sailor Moon, and you know, I like that he's NOT a carbon copy, sure, he's strong, sure, he sometimes cries and sometimes doesn't win at the start, but he does NOT back down!
Yumoto is a 16-year-old by the end of the series and I would really love to see the movie elaborate on his own strength and even the others, they deserve to shine.
