A rather shy boy who gets embarrassed easily. The slightest thing will make him cower in fear, especially things to do with horror or insects. Sengoku is very smart and serious, normally ranked #1 in terms of grades in the school (and #2 in phys ed). He’s polite and a people pleaser, usually puts others before himself. Class president. Sengoku also avoids swimming; in his case, he's self-conscious about how skinny he is and doesn't want to put his body on display. Sweet and quiet, but can be fun
