Chapter Summaries

Mahiro continued his intimate encounter with Sumire Muroto until Tina interrupted them at the door, then spent the next morning testing his AVG Serum-enhanced abilities in a spar with Enju Aihara.

Mahiro watched Seitenshi push through public opposition to enact the Gastrea New Law, then received her unexpected visit after she insisted that she needed his help with a national emergency.

• Koro Hotaru told Mahiro that Seitenshi would arrive at Arcadia in five minutes, and Mahiro went out to meet her as her limousine arrived.

Seitenshi visited Mahiro to learn whether she had won their wager, and he showed her the people who had attacked Arcadia and demanded the Cursed Children be driven out. After Seitenshi condemned them and collapsed, Mahiro turned the captured attackers into gold, leaving the children with their refuge secure and Seitenshi unconscious in his arms.

• Mahiro showed Seitenshi nearly a thousand bound captives who had called for Arcadia to be attacked and the Cursed Children expelled.
• Rita Sossbeni killed one captive who shouted at Seitenshi, and Mibu Asaka reported that the 931 remaining prisoners included 400 Japanese Pureblood Faction members who had attacked Arcadia with explosives and Molotov cocktails.

• Louise Sairazny praised Mahiro, while Rita Sossbeni called him a freak and offered to help.

Kisara confronted Rentaro at the Tendo estate, where Mahiro left her to continue her revenge and went to meet Tendo Kikunojo. Kikunojo admitted that he had used the Cursed Children as a barrier against Gastrea and ordered Kisara’s parents killed to protect the Tendo Family, while Mahiro pointed out that Kikunojo’s wife had died in the same incident.

• Mahiro told the children to live as usual, and Kayo worried that the Gastrea would soon overwhelm the Self-Defense Forces and Civil Security auxiliary troops.

• Seitenshi told Mahiro she sensed Kikunojo’s death and wept over her failures as the Tokyo Area’s leader.

• Hayama told Maya that Mahiro had been missing for exactly a month and asked whether he might have died as Tatsuya had concluded.
• Maya said she could feel that Mahiro was merely lost and made a bet with Hayama that he would return.
• Mahiro suddenly appeared in the room and fell unconscious on top of Maya, who embraced him and told Hayama that he had lost the bet.
• Maya decided not to notify Miyuki or the Saegusa Family, leaving Mahiro to explain his return to the girls himself.
• Mahiro woke and recalled using the ring’s teleportation function after Starfall Strike before losing consciousness.
• Mahiro realized he had been lying on Maya’s lap and asked her to let him sort out what had happened.

Mahiro reunited with Maya at the Yotsuba main house, told her about his month in another world, and gave her an enhancement serum that healed old injuries but did not restore her missing organs. When Mahiro asked for Mashima Island, Maya agreed and had the Mashiba Family transfer it to him.

Yotsuba Mahiro returned to campus after being missing for a month and reunited with Sayaka and Mayumi Saegusa, who had feared he was dead. He promised to explain what happened after school, then left Mayumi blushing and confused with a crude joke about an “ancestral DNA” gift.

• The others hesitated to accept the serums because they could improve magical aptitude, but Mahiro produced dozens more and Erika took one.

Erika, Mizuki, and several other girls received an injection that strengthened their bodies, and two months later Kitayama Shizuku prepared to study in the USNA. Maya Yotsuba warned Mahiro that Major Sirius had come to investigate Scorched Halloween and target him, while Shizuku departed for the United States.

• The five visited the stalls, bought candied apples, tried scooping water balloons, and climbed to the shrine courtyard.
• Mahiro sensed an unskilled observer watching him near the worship hall.

Mahiro confronted Lina after catching her spying at the shrine, while Lina later revealed her identity as USNA exchange student Angelina Kudou Shields at First High.

• Mari and Mayumi discussed Lina’s extraordinary magical ability with Mahiro, who waited for Tatsuya and the others before explaining what he knew.
