As Rimuru approached Shirou’s home, Alaya warned him that a powerful being from another world was approaching, and he saw Matou Sakura amid a lightning strike.

• Rin Tohsaka ordered Archer to remove his mask, but Rimuru refused and warned her not to treat him like a servant under her command.

Rimuru then accompanied Rin Tohsaka on reconnaissance, repaired her damaged house, and learned how tight the Tohsaka Family's finances had become.

Rimuru and Rin Tohsaka surveyed Fuyuki City from a rooftop while discussing Rin’s financial difficulties and the Holy Grail War’s likely participants. After considering whether he could exploit his Archer abilities to summon another Servant, Rimuru asked about Rin’s magical energy and urged her to leave a familiar behind to watch the rooftop.

• Rin explained that her inheritance and Magecraft studies had drained the Tohsaka family’s wealth, leaving her unable to research new Magecraft or patents.
• From a skyscraper in Shinto, Rimuru spotted Shirou Emiya and Illya meeting on a mountain road, but they passed without fighting.

• Rin felt dense magical energy upon entering the school and realized that someone had begun deploying a bounded field.
• Rimuru judged the bounded field amateurish but chose not to destroy it, while worrying that Red Fox might be powerful enough to defeat him.

Rimuru investigated the Soul-Eating Barrier while discovering that Shinji Matou had survived and was behind it.

• Shinji Matou asked Red Fox to give his Magic Crest to Sakura, but Red Fox refused and offered him a Flame Seed of Phoenix instead.

• Cú Chulainn pressed Rimuru with spear attacks, but Rimuru matched his technique using projected spears and repeatedly broke them to create throwing opportunities.

Rimuru followed Shirou Emiya to investigate the magical presence at his home and discovered Marisbury Animusphere, a Clock Tower Lord seeking the Holy Grail to fund humanity’s survival.
