(Spoiler from AP24)

Volume 5
 * Ikki went against his first round opponent, Yudai Moroboshi the previous winner of the Festival.
 * Ouma and Ikki fought in this Volume but Ikki was easily defeated (actually its pwned) by his brother.
 * Ikki defeats Yudai using Blade Steal (Edelweiss) + Ittou Shura/Rasetsu.
 * Stella was almost absent for the entire Volume and only returned at the end of the Volume.

Volume 6
 * Kuraudo vs Sara, Sara wins after owning Kuraudo.
 * Stella took one 4/5 opponents from Akatsuki as a punishment for being absent in the previous volume. (Can't remember the exact number of opponents)

Volume 8
 * 1) Ikki vs Amane and Stella vs Ouma in the semifinals.
 * 2) Stella's new power, the Noble Art Dragon Spirit activates by stabbing Laevateinn into herself and fuses with the sword to gain tremoundous physical strength.
 * 3) Ikki defeats Amane easily (not sure how).
 * 4) Ikki's heart stop beating after the match due to Amane wishing to die.
 * 5) Ikki wakes up 1 week(?) later but the tournament should've ended by that time, but didn't because of the support Ikki has gained so the finals was postponed.

Spoiler regarding Sara, Volume 7
 * She is hardcore fathercon. She is actually a world famous painter. She need Ikki's nude body in order to completed her and her father's greatest master piece and also she already get a permission and support from Stella to draw Ikki's naked body in exchange for her painting in the future.
 * Sara's father is already dead because he is to absorbed in creating a single master piece. In the beginning she hates drawing but started to draw more and more because she searched for a connection and bonding in order to understand her father.
 * The drawing that Sara promised for Stella is a drawing of herself and Ikki in a wedding dress for the royal palace portrait in the future if Ikki and Stella got married.
 * For Sara, Ikki's body=ideal body for men. She said to Stella that she doesn't have any feeling of love toward Ikki and even said that Stella and Ikki is perfect for each other and compliment her in order to get her to let Ikki be her model + the promised painting of a famous painter and Stella also can look at Ikki's nude body made her side with Sara despite Ikki's objection in this matter. Sara and Stella the chase after Ikki for whole night until Ikki hide in his brother's room.

Then a bit of Ouma, Volume 6.
 * Ikki apparently talked with his brother first to hide him in his room and explained the situation to him. He accepted with the condition of only 1 night and sheltered him. In there thay have a conversation as a sibling. In there we can truly see that they are sibling after all. In my opinion, they just like a normal sibling with a bad relationship. Ikki protest about him joined hand with a terrorist like group (akatsuki) and ouma just said that he was asked by their father to do this. Ikki just glad that he is still the same stoic brother whose purpose is only to be the strongest. Ouma also give the reason why he should stay away from Stella, he want Stella to see that there are more stronger people out there and want her to grow.
 * Ouma only wish is to fight a opponent that can make him go past his limit. Because Stella is stronger now, he doesn't have any kind of protest to their relationship anymore. Seeing Stella power he eagerly wants to fight with her.

Volume 9
 * Prior to the finals, most of Ikki's past rivals act as his sparring partner.
 * Ikki vs Stella in the finals.
 * Ikki undergoes awakening in the match.  (Don't ask what awakening is cause it isn't explain yet)  According to Edelweiss, he's the 2nd person to undergo awakening. Ikki awaken because he doesn't want Stella to find another rival besides him. (In short, jealousy)
 * Ikki defeats Stella and wins the tournament.
 * Edelweiss appears with 3 other people whom are called the Majin (again not explained in this volume)
 * Bakuga the Prime Minister of Japan is one of Rebellion's Twelve Apostles.
 * Ikki and Stella has sex after the finals.
 * Shizuku barges in after the sex. Yandere Shizuku appears.
 * But Stella says her yandere daddy is scarier than yandere Shizuku and Ikki will definitely die when he meets him but reassures Ikki that she'll only love him this life even if he dies. (I wonder if that means she'll still marry someone her parents decide on)
